4.1.7 Thermal imagers shall be listed to ANSI/ISA-12 .12.01, Nonincendive Electrical Equipment for Use in ClassI and II, Division 2 and Class III, Divisions 1 and 2 Hazardous (Classified) L ocations, and shall meet therequirements for at least Class I, Division 2, Groups C and D and Class II, Division 2, Groups F and G hazardouslocations, and with a Temperature Class of T3, T3A, T3B, T3C, T4, T4A, T5 or T6. For the purpose of theimpact test referenced in 15.4 of ANSI/ISA-1 2.12.01, NFPA 1801 shall be considered the applicable standard for products in unclassified locations.


There are three key aspects to this input - - 1) Relocate Clause 7.1.4 to a new clause under 4.1 on general certification requirements, 2) Expand the Division 2 certification requirement to include Class II, Division 2, Groups F and G, in addition to the existing Class I, Division 2 requirements, and 3) Include reference to the T3 and T4 temperature classifications that have "A" suffixes, in addition to the existing reference to T3, T4, T5 and T6. The rationale for 1) is because compliance with ANSI/ISA-12.12.01 includes requirements for product labeling, user information, and design requirements, in addition to performance requirements. As written and located within the current edition of NFPA 1801, it could be mistakenly assumed that only compliance with the performance requirements in ANSI/ISA-12.12,01 is required. To address this issue, comparable text to 7.1.4 could be added under 5.1, 5.2 and 6.1, in addition to 7.1.4, but simply addressing the issue of compliance with ANSI/ISA-12.12.01 solely under 4.1 seemed simpler with less potential for confusion. The rationale for 2) is because exposure to Class II explosive dust atmospheres is a concern for this equipment, in addition to exposure to Class I explosive gas atmospheres. Compliance with these Class II, Division 2 requirements mostly involves use of a NEMA Type 12 or better enclosure. The rationale for 3) is because T3A, T3B, T3C and T4A are permitted temperature classifications between T3 and T6 in both ANSI/ISA-12.12.01 and in the NEC.

4.2.9

The certification organization shall have a follow-up inspection program of the manufacturer’s facilities of thecompliant product with at least two random and unannounced visits per 12-month period to verify the product’scontinued compliance.

4.2.9.1

As part of the follow-up inspection program, the certification organization shall select sample compliant product atrandom from the manufacturer’s production line, from the manufacturer’s in-house stock, or from the openmarket.

4.2.9.2

Sample product shall be evaluated by the certification organization to verify the product’s continued compliancein order to ensure that the materials, components, and manufacturing quality assurance systems are consistentwith the materials, components, and manufacturing quality assurance that were inspected and tested by thecertification organization during initial certification and recertification.

4.2.9.3

The certification organization shall be permitted to conduct specific testing to verify the product’s continuedcompliance.

4.2.9.4

For products, components, and materials where prior testing, judgment, and experience of the certificationorganization have shown results to be in jeopardy of not complying with this standard, the certificationorganization shall conduct more frequent testing of sample product, components, and materials acquired inaccordance with 4.2.9.1 against the applicable requirements of this standard.


Whole chapter 4.2.9 can be removed.If chapter 7.1.4 is clarified so that certification to ANSI/ISA 12.12.01 is required, no follow-up inspection program is needed for NFPA1801.The ANSI/ISA12.12.01 ”Factory audit inspection” program, together with chapter 4.4.1 annual recertification will give the same effect. ANSI/ISA requires 4 yearly factory audit inspections. There is no need for additional NFPA1801 follow-up inspections above the annual NFPA1801 recertification and four factory audit inspections for ANSI/ISA.

If the manufacturer supplies a power source that is capable of operating for a minimum of 120 minutes or greater they should be able to provide the estimated level of power associated with each of the four segments in time. It should be noted that the operating time of a fully charged power source currently supplied in many thermal imagers far exceeds 120 minutes.

Minimum video refresh rate

All thermal imagers shall have a minumum video refresh rate of 30 frames per second.


The original intent of the document was to require video refresh rates of 30Hz or higher. This was discussed and included in the pre-NFPA technical document but was lost somewhere along the line. A low refresh rate camera will pass the NFPA 1801 image quality tests since all the NFPA testing is done on static images. A refresh rate of less than 30Hz can make navigation more difficult and may lead to firefighter disorientation.

We require that the thermal imager shall be provided with a method of attaching the thermal imager to the user, and the method of attachment shall not degrade the function or performance of the thermal imager but no where in the standard do we test for this.It is importaint to have have 6.1.7 as today most thermal imagers should and are intended to be attached to the user, possibly by a retractable lanyard or strap rather than to just be hand held. It is understood that there are several methods of attachement and it would be counterproductive to the process to have a manufactuer submitt all specimens with all the attachement variations for all the testing. It is recommended that each means of attachment that a manufacturer offers be be supplied to the testing lab and that the testing lab simply attach them to the thermal imager as intended and then to the person as intended by the manufactuer to determine if either the attachement point on the thermal imager and/or the method of attachement degrades the function or performance of the thermal imager.

6.2.1.1

The power–on/off button shall be capable of being switched by a gloved hand. The gloves used for this functiontest shall be contructed from American cow hide and include a PTFE moisture barrier and shall comply withstructural fire-fighting glove requirements of NFPA 1971, Standard on Protective Ensembles for Structural FireFighting and Proximity Fire Fighting.


The requirements for the gloves used for the power button test are not specific enough. The NFPA 1971 requirement for a structural fire fighting glove is a minimum requirement. Many firefighters choose to wear gloves that offer additional protection but are less compliant (flexible), making it more difficult to push buttons on the TIC. The "gloved hand" requirement should not be based on just the minimum glove requirements.

Thermal Imagers shall be tested for spot temperature accuracy, to verify design requirement in Section 6.6.4.1.6when viewing a small object.

Thermal Imagers shall be tested for relationship of colour to temperature to verify design requirement 6.6.4.2.


The specification is open to certifying a camera that can show an incorrect spot temperature due to failing to change sensitivity mode. The camera may therefore show the maximum temperature of ‘high sensitivity mode ‘say 300F while viewing a small hot object at 800F, therefore misleading the user. The same issue applies to colour related temperature.A suitable test method will require definition, but this could also be used to validate the requirement that colours are not repeated in the temperature range

The products should be CERTIFIED to ANSI/ISA 12.12.01. Motivation: Statement from Stephen Sanders, Technical Director SEI (Safety Equipment Institute) ([email protected]): With regard to Section 7.1.4 of NFPA 1801-2013 and the need for certification vs. testing to the ANSI/ISA 12.12.01 standard… SEI has required “certification” for electronics to the various intrinsic safety and/or hazloc standards, as opposed to just testing to the requirements in the applicable standard.SEI’s rationale for requiring certification relies upon SEI understanding of the intent of the NFPA Technical Committees. In addition to NFPA 1801-2013, requirements for compliance of electronics with intrinsic safety standards exist in other similar NFPA standards, including both NFPA 1981-2013 (SCBA) and NFPA 1982-2013 (PASS). Both of these standards specifically require certification for electronics. While NFPA 1801-2013 may utilize the word “tested” in Section 7.1.4, we believe that it was the intent of both the NFPA Electronics Safety Equipment Technical Committee and its parent committee, the Correlating Committee, that a TIC’s electronics be certified (which of course includes testing/evaluation and follow-up factory visits) as opposed to just being tested.

For the purpose of the impact test referenced in 15.4 of ANSI/ISA 12.12.01, NFPA 1801shall be considered the applicable standard for products in unclassified locations.


The key aspect to this input is that it is not simply deleting 7.1.4, but instead is relocating Clause 7.1.4 to a new clause under 4.1 on general certification requirements (along with making some proposed revisions to the text as well). The rationale for relocating 7.1.4 is because compliance with ANSI/ISA-12.12.01 includes requirements for product labeling, user information, and design requirements, in addition to performance requirements. As written and located within the current edition of NFPA 1801, it could be mistakenly assumed that only compliance with the performance requirements in ANSI/ISA-12.12,01 is required. To address this issue, comparable text to 7.1.4 could be added under 5.1, 5.2 and 6.1, in addition to 7.1.4, but simply addressing the issue of compliance with ANSI/ISA-12.12.01 solely under 4.1 seemed simpler with less potential for confusion.

The display area from which the samples are taken is not generally large enough to take samples from the left and right sides. In practice, the samples have significant overlap and there is no real difference between left and right. The requirement was likely a relic from the NFPA 1981 SCBA face piece lens abrasion test where there could be significant differences from the right and left sides. Eliminating the extra samples saves time and money.

Annex X Explosion Protection Requirements for Electronic Safety Equipment

This annex is not a part of the requirements of this NFPA document but is included for informational purposes only.

X.1 Introduction. This NFPA standard includes requirements that define the level of explosion protection necessary for the electronic safety equipment under the scope of the standard. .

These explosion protection requirements include a normative reference to an American National Standards Institute (ANSI) standard for a protection technique for hazardous (classified) locations as defined in the National Electrical Code (NEC), ANSI/NFPA 70.

Note: See Articles 500, 505 and 506 of the NEC for additional details.

X.2 Overview of Hazardous (Classified) Locations. According to the NEC, there are two systems under which hazardous locations can be classified – the Division system and the Zone system. Under either system, hazardous locations are classified based on the following attributes:

Type of explosive atmosphere

Likelihood that the type of explosive atmosphere is present when equipment is operating

Ignition-related properties of the type of explosive atmosphere

Maximum surface temperature of the equipment under operating conditions

Under the Division and Zone systems, the following are three types of explosive atmospheres in accordance with the NEC:

Class I: Flammable gases, flammable liquid–produced vapors, & combustible liquid–produced vapors.

Class II: Combustible dusts.

Class III: Ignitable fibers/flyings.

Note: The terms “Class II” and “Class III” are only used under the Division system as a means to designate these explosive atmospheres. These terms are not used under the Zone system. Under the Zone system, the Zone and Group designations noted below are used to designate explosive atmospheres that involve combustible dusts or ignitable fibers/flyings.

Under the Division system, the following are designations indicating the likelihood that the type of explosive atmosphere is present when equipment is operating:

Division 1: The explosive atmosphere can exist all of the time or some of the time under normal operating conditions.

Division 2: The explosive gas or dust atmosphere respectively is not likely to exist under normal operating conditions.

Under the Zone system, the following are designations indicating the likelihood that the type of explosive atmosphere is present when equipment is operating:

Zone 0 or Zone 20: The explosive gas or dust atmosphere respectively is present continuously or for long periods of time under normal operating conditions.

Zone 1 or Zone 21: The explosive gas or dust atmosphere respectively is likely to exist under normal operating conditions.

Zone 2 or Zone 22: The explosive gas or dust atmosphere respectively is not likely to exist under normal operating conditions.

Note: The likelihood that an explosive atmosphere is present based on a Division 1 designation is the same as the combination of a Zone 0 and a Zone 1 designation, or of a Zone 20 and a Zone 21 designation. The likelihood that an explosive atmosphere is present based on a Division 2 designation is the same as a Zone 2 or a Zone 22 designation.

Under the Division system, the following are designations indicating the ignition-related properties of Class I explosive gas atmospheres:

Group A: Acetylene explosive gas atmosphere.

Group B: Explosive gas atmosphere mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value less than or equal to 0.45 mm or a minimum igniting current ratio (MIC ratio) less than or equal to 0.40. The representative test gas for Group B is hydrogen.

Group C: Explosive gas atmosphere mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value greater than 0.45 mm and less than or equal to 0.75 mm, or a minimum igniting current ratio (MIC ratio) greater than 0.40 and less than or equal to 0.80. The representative test gas for Group C is ethylene.

Group D: Explosive gas atmosphere mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value greater than 0.75 mm or a minimum igniting current ratio (MIC ratio) greater than 0.80. The representative test gas for Group D is propane.

Under the Zone system, the following are designations indicating the ignition-related properties of Class I explosive gas atmosphere:

Group IIC: Explosive gas atmosphere containing acetylene, hydrogen, or flammable gas, flammable liquid–produced vapor, or combustible liquid–produced vapor mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value less than or equal to 0.50 mm or minimum igniting current ratio (MIC ratio) less than or equal to 0.45. The representative test gases for Group IIC are acetylene and hydrogen. Group IIC is equivalent to a combination of Group A and Group B.

Group IIB: Explosive gas atmosphere containing acetaldehyde, ethylene, or flammable gas, flammable liquid–produced vapor, or combustible liquid–produced vapor mixed with air that may burn or explode, having either maximum experimental safe gap (MESG) values greater than 0.50 mm and less than or equal to 0.90 mm or minimum igniting current ratio (MIC ratio) greater than 0.45 and less than or equal to 0.80. The representative test gas for Group IIB is ethylene. Group IIB is equivalent to Group C.

Group IIA: Explosive gas atmosphere containing acetone, ammonia, ethyl alcohol, gasoline, methane, propane, or flammable gas, flammable liquid–produced vapor, or combustible liquid–produced vapor mixed with air that may burn or explode, having either a maximum experimental safe gap (MESG) value greater than 0.90 mm or minimum igniting current ratio (MIC ratio) greater than 0.80. The representative test gas for Group IIA is propane. Group IIA is equivalent to Group D.

Note: Equipment marked “IIB” is suitable for applications requiring Group IIA equipment. Similarly, equipment marked “IIC” is suitable for applications requiring Group IIA and Group IIB equipment. When the electrical equipment is for use in a particular gas in addition to being suitable for use in a specific gas group, the chemical formula shall follow the group and be separated with the symbol “+”, for example, “IIB + H2”.

Under the Division system, the following are designations indicating the ignition-related properties of Class II explosive dust atmospheres:

Group E: Explosive dust atmosphere containing combustible metal dusts, including aluminum, magnesium, and their commercial alloys, or other combustible dusts whose particle size, abrasiveness, and conductivity present similar hazards in the use of electrical equipment. The representative test dust for Group E is magnesium dust.

Group F: Explosive dust atmosphere containing combustible carbonaceous dusts that have more than 8 percent total entrapped volatiles, or that have been sensitized by other materials so that they present an explosion hazard. Coal, carbon black, charcoal, and coke dusts are examples of carbonaceous dusts. The representative test dust for Group F is coal dust.

Group G: Explosive dust atmosphere containing combustible dusts not included in Group E or Group F, including flour, grain, wood, plastic, and chemicals. The representative test dust for Group G is grain dust.

Note: There are no group designations for Class III explosive atmospheres under the Division system.

Under the Zone system, the following are designations indicating the ignition-related properties of explosive dust atmospheres:

Group IIIC: Explosive dust atmosphere containing combustible metal dust. Group IIIC is equivalent to Group E.

Group IIIB: Explosive dust atmosphere containing other than combustible metal dust. Group IIIB is equivalent to Groups F and G.

Group IIIA: Explosive fibers/flyings atmosphere containing solid particles, including fibers, greater than 500 μm in nominal size, which may be suspended in air and could settle out of the atmosphere under their own weight. Group IIIA is equivalent to Class III.

Under the Division system, the following are the designations indicating the maximum surface temperature of the equipment under operating conditions:

Class I and II Class III

X.4 Determining the Applicable ANSI Explosion Protection Standard. While there may be a common ANSI explosion protection standard referenced for most electronic safety equipment, there is not necessarily only one ANSI explosion protection standard that is always applicable to all electronic safety equipment.

This is because the use of electronic safety equipment in the field by emergency services personnel does not directly relate to any one hazardous (classified) location. For example:

As noted earlier in the Overview, hazardous locations are classified as defined by the NEC based on the likelihood that the type of explosive atmosphere is present when equipment is operating.

Division 1 classification is associated with atmospheres that can exist all of the time or some of the time under normal operating conditions. Division 2 classification is associated with atmospheres that are not likely to exist under normal operating conditions.

For most of the life of a piece of electronic safety equipment, it may reside in an unclassified location (such as in a fire house), but it is not being used in such locations.

When a piece of electronic safety equipment is used in the field, it is often used in unclassified locations, but due to an abnormal condition these unclassified locations either have an explosive atmosphere present or have the potential for an explosive atmosphere being present.

Therefore, for a significant portion of its operation and use in the field, electronic safety equipment may be exposed to explosive atmospheres or have the potential of being exposed to explosive atmospheres.

However, even when exposed to an explosive atmosphere in the field, electronic safety equipment is only exposed for a limited period of time for any one field event.

In addition, electronic safety equipment may be used in the field in actual hazardous (classified) locations.

Use of electronic safety equipment in such unclassified potentially explosive atmospheres has some similar characteristics to electronic equipment used in actual hazardous (classified) locations. However, while there are some similar characteristics, there are also dissimilar characteristics. Therefore, as noted above, a direct comparison to a specific hazardous (classified) location is not possible.

Therefore, since a direct comparison between electronic safety equipment used in unclassified potentially explosive atmospheres and general electronic equipment used in hazardous (classified) locations is not possible, the risk of explosion requirements should reflect the highest level of explosion protection possible in

accordance with the NEC, while not adversely restricting the performance characteristics needed by emergency personnel.

The highest level of explosion protection, under either the Division or Zone systems, that could be applicable to electronic safety equipment is Division 1 or Zone 0 Intrinsic safety. Since the Division system is significantly more broadly used in the US in comparison to the Zone system, it is recommended that the initial consideration of the applicable ANSI explosion protection standard begin with ANSI/UL 913 or ANSI/TIA 4950-A. However, after this initial consideration, additional consideration is necessary regarding whether or not any Division 1 Intrinsic safety requirements will adversely restrict the performance characteristics needed by emergency personnel.

For example, Division 1 Intrinsic safety requirements are more restrictive regarding available power from a battery than Division 2 Nonincendive requirements. Therefore, if such a restriction regarding power from a battery could adversely restrict necessary performance characteristics, then ANSI/ISA-12.12.01 would provide the highest level of explosion protection possible in accordance with the NEC, while not adversely restricting the performance characteristics needed by emergency personnel.

As another example, later editions of ANSI/UL 913 (such as the 8th edition) include restrictions on continuous transmission power, while ANSI/TIA 4950-A and earlier editions of ANSI/UL 913 (such as the 5th edition) do not. Therefore, if such a restriction regarding transmission power could adversely restrict necessary performance characteristics, then ANSI/TIA 4950 or earlier editions of ANSI/UL 913 would provide the highest level of explosion protection possible in accordance with the NEC, while not adversely restricting the performance characteristics needed by emergency personnel.

Electronic safety equipment should be regularly subjected to such a consideration regarding explosion protection requirements versus necessary performance characteristics, with a different determination regarding the applicable ANSI explosion protection standard being reasonably possible based on technological advances in electronic safety equipment.

If the above Annex X is accepted, consideration should be given to adding the following standards to Chapter 2 (or maybe creating a referenced publications section under this Annex):

‒ ANSI/UL 913, Intrinsically Safe Apparatus and Associated Apparatus for Use in Class I, II, and III, Division 1, Hazardous (Classified) Locations

‒ ANSI/TIA 4950-A, Requirements for Battery-Powered, Portable Land Mobile Radio Applications in Class I, II, and III, Division 1, Hazardous (Classified) Locations

‒ ANSI/UL 60079-0, Explosive Atmospheres - Part 0: Equipment - General Requirements ‒ ANSI/UL 60079-7, Explosive Atmospheres- Part 7: Equipment Protection by Increased Safety "e" ‒ ANSI/UL 60079-11, Explosive Atmospheres - Part 11: Equipment Protection by Intrinsic Safety "i" ‒ ANSI/UL 60079-15, Explosive Atmospheres - Part 15: Equipment Protection by Type of Protection "n" ‒ ANSI/UL 60079-18, Explosive Atmospheres - Part 18: Equipment Protection by Encapsulation "m" ‒ ANSI/ISA 60079-31, Explosive Atmospheres - Part 31: Equipment Dust Ignition Protection by Enclosure

"t"

Also, if the above Annex X is accepted, consideration should be given to adding the following definition to Chapter 3 (or maybe creating a definitions section under this Annex):

‒ Intrinsic safety – Type of protection where any spark or thermal effect is incapable of causing ignition of a mixture of flammable or combustible material in air under prescribed test conditions.

‒ Nonincendive equipment – type of protection where equipment having electrical/electronic circuitry is incapable, under normal operating conditions, of causing ignition of a specified flammable gas–air, vapor–air, or dust–air mixture due to arcing or thermal means.

‒ Encapsulation “m” – Type of protection where electrical parts that could ignite an explosive atmosphere by either sparking or heating are enclosed in a compound in such a way that this explosive atmosphere cannot be ignited.

‒ Increased safety “e” – Type of protection applied to electrical equipment that does not produce arcs or sparks in normal service and under specified abnormal conditions, in which additional measures are

applied so as to give increased security against the possibility of excessive temperatures and of the occurrence of arcs and sparks.

‒ Protection by enclosure “t” – Type of protection for explosive dust atmospheres where electrical apparatus is provided with an enclosure providing dust ingress protection and a means to limit surface temperatures.
