Roles and ResponsibilitiesRoles and Responsibilities

Program Administrator

- responsible for all aspects of program includingrole assignments, risk assessments, list of

respirators used, training, program maintenance,

annual reviews, and development of emergency

procedures.


6/57


User

- following the requirements of the RPP including

checking respirators before use, seal checking,

and reporting issues


7/57


Supervisor

- ensures that the provided elements of the RPP are in

place (e.g. health screening, fit testing, training)

- notifies the program administrator of issues/concerns


8/57


Fit tester(e.g.qualifications, record keeping)

Maintenance Personnel (e.g. maintaining, repairing respirators,record keeping)

Health Care Professional (e.g. assesses suitability of the user to the

selected respirator and provides findings to program administrator)

Hazard AssessmentHazard Assessment

Definition:

A hazard is a condition or practice with a

potential for injury to people or damage to

equipment, materials or the environment


10/57


Airborne Contaminants

Oxygen Deficiency (or enrichment)


11/57

Hazard AssessmentHazard AssessmentExamples of Airborne Contaminants

Carbon monoxide: vehicular traffic, forklifts

Lead: gun ranges, battery plants, radiatorshops, abrasive blasting

Solvents: spray painting, furniture stripping,coating manufacturing, floor finishing,adhesives, sealants


12/57


Metal fumes: foundries, welding

Silica: abrasive blasting, concrete cutting,

foundries, ceramics

Expired air

~ 16% O2

~ 4% CO2

exchange of oxygen between blood and external

atmosphere by enriching the blood with oxygen during

inhalation and removing CO2 from blood during exhalation.

Hazard AssessmentHazard AssessmentConsiderations:

Contaminants

Concentration

Exposure Limit

Odour (warning properties), Irritation

Absorption through skin, eyes


18/57


Determination of Airborne Concentration?

Air sampling

Mathematical modeling, estimation

Experience

If unknown assume the worst


19/57


IDLH (Immediately Dangerous to Life or Health)

An atmosphere that poses an immediate threat to life, would cause irreversible health

effect(s), or would impair escape


20/57


IDLH Assumptions:

Structural firefighting

Untested confined space

Known hazardous contaminant(s) at unknown concentration(s)

Oxygen level

Qualified person assessment

Chemical Cartridge LimitationsChemical Cartridge Limitations

Limitations

Cartridges are specific!

Limited sorbent capacity not for IDLH situations Water vapour

Must have adequate warning properties (substances

odour, taste or irritation effects are detectable and

persistent at concentrations at or below theoccupational exposure limit)

No oxygen supplied

Reduced sorbent/filter life due to continuous air

flow

Dust loading on filter reduces air flow

High work rates negative pressure in helmet

APFAPF

Assigned Protection FactorsAssigned Protection FactorsDEFINITION:

The minimum anticipated protection provided by a

properly functioning respirator or class ofrespirators to a given percentage of properly

fitted and trained users.

TWAEV (exposure limit) x APF = maximum

concentration of contaminant against which a

particular respirator may be used

Qualitative Fit Test (QLTF)Qualitative Fit Test (QLTF)

A fit test where the person wearing a respirator is

exposed to an odorous vapour, or another

suitable test agent. The respirator wearer useshis or her senses to detect any leakage of the

test agent into the face piece.
