Oregon DPSST Security Professional Practice Test

In order to reduce explosion risk when it comes to hazardous areas where dangerous substances are present, a security guard must

1. Be aware of the areas of the site that house hazardous materials

2. Be familiar with the properties of the hazardous materials

3. Be aware of safe handling procedures

4. All of the above

The correct answer is: All of the above

The correct answer is "All of the above," because every listed choice could help reduce the risk of explosions in areas where hazardous substances are present. This comprehensive approach accounts for various aspects of risk management in these types of environments. Being aware of the areas within a site that houses hazardous materials (option A) means that the security guard can make sure these areas are secure and that unauthorized individuals don't accidentally enter and create risk. Being familiar with the properties of the hazardous materials (option B) adds an additional layer of safety. Different materials can behave in different ways so having a basic understanding of what it is dealing with will enable the security guard to respond to incidents involving those substances more effectively. Finally, being aware of safe handling procedures (option C) is vitally important. Even when security guards are primarily tasked with securing the site, they should still be aware of how to handle the substances in emergencies. So the combined knowledge of the locations, properties and handling procedures of hazardous materials, will contribute to the overall reduction of the explosion risk, hence the correct answer is "All of the above".
