CSS Risk & Hazard Control 2

Question 1

Which risk assessment methodology uses a matrix to plot likelihood against consequence severity?

Accepted Answer

Risk probability-severity matrix

Answer

A risk probability-severity matrix plots the likelihood of an event against its potential severity to prioritize hazard controls.

Question 2

The substitution method of hazard control involves:

Accepted Answer

Replacing a hazardous substance or process with a less hazardous one

Answer

Substitution replaces a hazardous material or process with a safer alternative, making it the second most effective control after elimination.

Question 3

A residual risk is best defined as:

Accepted Answer

Risk remaining after all feasible controls have been implemented

Answer

Residual risk is the level of risk that remains after all practicable control measures have been put in place.

Question 4

When conducting a Job Hazard Analysis (JHA), the first step is to:

Accepted Answer

Select the job to be analyzed

Answer

The first step in a JHA is selecting the job to be analyzed, typically prioritized by frequency of accidents, severity potential, or new tasks.

Question 5

Which chemical hazard control measure is considered an engineering control?

Accepted Answer

Local exhaust ventilation (LEV)

Answer

Local exhaust ventilation is an engineering control that captures and removes airborne contaminants at the source before workers can be exposed.
