INCREASED SAFETY MEASURES IN RESPONSE TO COVID-19

OUR ROUTINE SAFETY STANDARDS ALREADY PROTECT OPERATORS FROM COVID-19

CLOUD-BASED DATA STORAGE WITH IMMEDIATE & AUTOMATIC REPORTINGFELL FIELD OPERATIONS: COVID-19 SAFETY UPDATES All field operations are performed independently, by a Certified Electro Scan Operator. No direct interaction with your personnel is ever needed. The Electro Scan Operator meets the jet nozzle after it mobilizes upstream from the downstream manhole. Once the jet nozzle is pulled up from the manhole, the Sliding Funnel Plug and Electro Scan ES-620 Probe are attached to the hose, and all equipment is lowered back into the manhole. Once the desired water height is achieved, the Jet Truck Operator pulls the equipment through the pipe to the downstream manhole to complete the inspection. Upon completion, the Jet Truck Operator removes the Sliding Funnel Plug and disconnects the jet hose from the Electro Scan Probe. The Electro Scan Probe is then pulled back through the pipe by the Electro Scan Cable and Reel. The Operators trade the jet nozzle and Sliding Funnel Plug by leaving equipment 6 feet from each other before retieving and moving to the next pipe segment for inspection.Data is collected without delay and fed through the coaxial cable back to the Mainline Application on a laptop computer in the Electro Scan Truck. Once the scan is completed, the data is uploaded via on board wifi to the cloud-based Critical Sewers® application where it will be instantly processed and available for viewing.

• Each Operator Has Own Vehicle• Operators are 6-feet Apart at All Times• Hand Sanitizer Station in Front and Rear of Vehicles

These additional safety measures meet or exceed the Center for Dis-ease Control recommendations for response to COVID-19. The most important requirement, which we are taking very seriously, is for our employees to be able to work together, but physically separated from each other. • Due to job specialization, only one (1) employee touches or uses any equipment as per their job function for that day. At the end of each day, all

equipment is cleaned and disinfected.• Required Personal Protective Equipment (PPE): steel-toed boots, hi vis and reflective apparel, gloves (chemical resistant, 9 mil thick), & hard hat.• Additional PPE includes eye protection, disposable masks (N95), extra clothing, etc., as recommended by CDC, NIH, & OSHA.• All PPE kits are personally assigned to an Operator, and kits have dedicated place to keep personal PPE from others. Extra PPE kits and equipment are

available on all vehicles.• Hand sanitizer is in the front door wells and also on rear of every truck. • Hand washing stations are on every truck.• All Trucks are fully stocked with spray and wipe disinfectants for use after each day’s work.• Each day all trash and used equipment (gloves, wipes, rags, etc.) is bagged and removed from the trucks to insure each day begins clean.

• Each Field Operator has vehicle assigned for each day, and its disinfected at the end of each day.• Before each day begins a tail gate safety meeting takes place, with appropriate social distancing of at least 6-feet, to go over the job and reiterate the

safety protocols in place and to be followed.• Each employee has reviewed and signed off on the current guidance from the CDC, NIH on appropriate disinfection requirements, techniques, and PPE

requirements for working in sewers and to protect themselves from COVID-19.

ADDITIONAL PRECAUTIONS IN RESPONSE TO COVID-19

Electro Scan Inc.Global Health & SafetyMeasures

FIELD OPERTIONS: COVID-19 SAFETY UPDATESAll field operations are performed independently by Certified Electro Scan Technicians with no direct interaction with third-party personnel or customers required. The Electro Scan Operator efficiently and effectively manages all equipment, including insertion, navigation, and retrieval. The highest priority of Electro Scan staff – during alll aspects of the sewer or water survey – is to safe-guard and protect the environment, deliver value-for-money to utility customers, avoid vehicle hazards, and protect pedestrians.

Electro Scan technology represents a machine-intelligent, non-destructive, leak detection solution. All data is collected without delay and instantly filtered through multiple security firewalls utilizing multiple redundant data storage backups with all data transport messaged using strict data protection algorithms, standards, and stored procedures. Once a sewer or water scan is completed, data is uploaded via onboard WiFi communication via data encrypted pathways delivered to either the Company’s CriticalSewers® or CriticalH2O cloud application where data can be instantly processed and available for review or decision support.
