CSS Risk & Hazard Control

Question 1

What is the first step in controlling workplace hazards?

Accepted Answer

Identifying and assessing hazards

Answer

The first and most fundamental step in controlling workplace hazards is identifying and assessing them. Before any corrective action can be taken, it is essential to recognize what hazards exist, where they are located, and who might be affected. This initial assessment allows for a thorough understanding of the risks involved, which then guides the selection and implementation of the most effective control measures to ensure worker safety.

Question 2

What is an example of hazard elimination?

Accepted Answer

Replacing chemical substances with safer alternatives

Answer

Hazard elimination is the most effective control measure, as it completely removes the hazard from the workplace. By replacing a dangerous chemical with a non-hazardous or less hazardous alternative, the risk of exposure and harm is entirely eliminated. This proactive approach prevents the hazard from ever causing an incident, making it the preferred method in the hierarchy of controls.

Question 3

What is the purpose of engineering controls in hazard control?

Accepted Answer

To limit employee exposure to hazards through machine design

Answer

Engineering controls involve making physical changes to the workplace or equipment to reduce or eliminate exposure to hazards. This means designing or modifying machinery, processes, or the work environment itself to inherently make it safer. Examples include installing ventilation systems, machine guards, or noise enclosures, which isolate people from the hazard or remove the hazard at its source through design.

Question 4

What is the role of administrative controls in risk management?

Accepted Answer

Altering the work schedule to avoid risk exposure

Answer

Administrative controls are changes to work procedures or practices that reduce exposure to hazards, without physically altering the hazard itself. Altering the work schedule, such as rotating job assignments or limiting time in hazardous areas, is a prime example. These controls manage how and when workers interact with a hazard, rather than eliminating or isolating it through engineering.

Question 5

How can personal protective equipment (PPE) reduce workplace risks?

Accepted Answer

By protecting workers from exposure to hazards

Answer

Personal Protective Equipment (PPE) serves as the last line of defense in the hierarchy of controls. It does not eliminate the hazard but creates a barrier between the worker and the hazard, thereby protecting the individual from direct exposure. Examples like safety glasses, gloves, or respirators are designed to prevent injury or illness when other control measures are insufficient or impractical.
