Study Notes

Responsibility for Labelling

Manufacturers are accountable for the correct labelling of hazardous substances they produce locally.
Importers, distributors, or retailers are responsible for the labelling of hazardous substances imported for local distribution.
When hazardous substances are repackaged by distributors, wholesalers, or retailers, they assume labelling responsibility.
Employers must label hazardous substances used in their workplace that are not supplied by manufacturers or distributors.
Employers must properly label substances transferred to new containers and identify unlabeled substances they receive.

Labelling Guidelines

Labels should retain product symbols and names, statements of hazards, and precautionary measures for any additional risks.
Condensed labels exempt precautionary measures clearly shown in hazard statements.

Testing and Ventilation

Workroom atmospheres must be tested annually for toxic dust, fumes, and vapors to ensure they remain within safe thresholds.
Ventilation and exhaust equipment require regular inspection and testing for safety and operational efficiency.

Dust Control

Design workplaces to minimize dust accumulation; frequent cleaning is required.
Clean dust-producing areas daily with vacuum equipment, especially in locations where flammable dust is processed.
Floors should be smooth, impervious, and easy to clean; loose materials that can trap dust should be avoided.

Workplace Hygiene

Areas where toxic or irritating substances are handled must be cleaned daily outside of work hours.
Workers must wash hands and faces before eating or leaving premises to prevent contamination.
Consumption of food, drink, or tobacco in workrooms is prohibited.
Workers must report any physical complaints related to exposure to toxic substances.

Emergency Protocols

Install warning devices in workplaces handling hazardous substances to alert personnel of potential danger.
Provide training for workers on emergency procedures, including pollution control and evacuation.

Handling of Hazardous Materials

Corrosive substances should be moved in bulk using safe systems to prevent spillage from small containers.
Tanks for hot or corrosive liquids must be equipped with proper drainage systems and containment measures to prevent leaks.
Above-ground non-flammable liquid storage tanks require protective measures, including surround pits to manage spills.

Lead Safety Measures

Properly designed local exhaust systems must be in place to control lead dust and fumes.
Workers handling lead should be provided with personal protective equipment (PPE) at no cost, which must be properly maintained.
Smoking, eating, or storing food in areas where lead is handled is prohibited.
Suitable storage lockers and washing facilities must be available for workers exposed to lead.
