Elimination/Substitution
What is the goal of elimination in controlling heat stress hazards?
To completely remove the heat source from the workplace.
What are 3 common types of engineering controls for heat hazards?
Ventilation, air conditioning, barriers (awning, screens, canopy etc.).
What are 3 examples of administrative controls used to prevent heat stress?
Modified work/rest cycles, training, monitoring programs, acclimatization, hydration policies.
What are 3 characteristics of clothing that should be required for workers to wear when working in the summer heat?
Lightly coloured, long sleeve, light weight, loose fitting, cotton.
Why can elimination be difficult in industries like industrial kitchens?
Because heat is needed for the job. Ovens, grills, etc.
In what case should fans NOT be used?
If the air temperature is at or above body temperature because it will expose the body to more hot air and increase the heat load.
What 3 areas should workers be trained on regarding heat stress?
Signs and symptoms of heat stress, first response and work restrictions.
What type of clothing can protect against radiant heat?
Reflective clothing.
How does regular maintenance and repairs of equipment help reduce heat stress in the workplace?
It can prevent heat from escaping through leaks, stopping heat at the source.
What section of the Saskatchewan Occupational Health and Safety Regulations refers to Ventilation?
Section 6-2, 6-3, 6-4.
How much and how often should a worker drink of fluid to replace fluid lost.
One cup every 15-20 minutes.
Why is PPE considered the least effective control method compared to elimination and engineering controls?
It does not remove the hazard, only protects the worker and relies on proper use and compliance.
