Hazardous Substance - Chronic

Workplace exposure to substances that can cause lethal disease over time (e.g. silica, arsenic, lead, welding fumes, asbestos, acid mist, etc.).  

Access Control

Are concentrated hazardous substances only stored & used in designated areas?

Am I authorized to work in the area where the hazardous substance is present?

Handling Requirements

Do I know the composition  of the material that I'm handling?

Is clean-up performed in a way that minimizes exposures to hazardous substances? (e.g. vacuum or wet clean-up of hazardous dust rather than compressed air)

Are components parts and equipment that might be contaminated with a high-hazard substance cleaned prior to maintenance activities?

Engineered Controls

Are ventilation systems working as designed, and effectively controlling airborne hazards?

Is my cab or control room properly maintained to ensure clean air, including effective air filters, weather stripping, door seals, etc.?

Is water being used effectively to control dust emissions?

Do I understand the operational conditions required to prevent unintended release? (e.g. safe ph. range, operating temperature, cell voltage, solution concentration, etc.)

Are process enclosures adjusted and maintained to ensure hazardous substances are contained properly (e.g. conveyor skirting, heat-retention balls, inspection doors closed, etc.)

PPE

Do I know when and where respirators are required?

Am I using the correct type of PPE for the task being performed? Note: check ratings, selection and use

Do I understand all of the identified health hazards in my area?

Have I ensured that the PPE is in good condition prior to use?
