Why is substitution considered a key strategy in controlling hazardous exposures?

1. Because it is the least expensive method

2. Because it directly reduces the amount of hazardous waste produced

3. Because it eliminates the source of the hazard by using safer alternatives

4. Because it makes compliance with regulations easier

The correct answer is: Because it eliminates the source of the hazard by using safer alternatives

Substitution is considered a key strategy in controlling hazardous exposures because it eliminates the source of the hazard by replacing it with safer alternatives. This is more effective than simply reducing the amount of hazardous waste produced, as it completely eliminates the potential for exposure. Additionally, substitution is not necessarily the least expensive method, as it may require an initial investment in new materials or processes. It also goes beyond just complying with regulations, as it proactively addresses and reduces the risk of hazards.
