Safety Showers And Eye Washes

Explanation
To be effective, showers and eye washes should supply a flow of water for at least 15 minutes. This is because it takes time to thoroughly rinse off any hazardous substances that may have come into contact with the body or eyes. A shorter duration may not be sufficient to completely remove the harmful substance, potentially leading to further injury or complications.

Explanation
The given statement suggests that most incidents that require the use of a shower or eye wash are caused by carelessness. This implies that these incidents could have been prevented if proper precautions were taken. Therefore, the correct answer is true, indicating that carelessness is a significant factor in such incidents.

Explanation
Consulting the SDS (Safety Data Sheet) is a good way to determine whether the chemical you are using is hazardous. The SDS provides detailed information about the chemical's properties, potential hazards, safe handling procedures, and emergency response measures. It also includes information on the chemical's toxicity, flammability, reactivity, and any special precautions that need to be taken. By consulting the SDS, you can make an informed decision about the potential hazards associated with the chemical and take appropriate safety measures to protect yourself and others.

Explanation
In order to prevent harmful gases or odors from entering the safety shower area, water should be kept in the trap of the drain. The trap acts as a barrier, preventing the gases from flowing back into the shower area. Therefore, it is important to keep water in the trap to ensure the safety and effectiveness of the safety shower.

Explanation
Leaving clothes on while helping a splash victim shower would not prevent residual contamination from remaining in the cloth. If the clothes are contaminated, they should be removed and properly disposed of to avoid further spread of the contamination. Therefore, the correct answer is False.

Explanation
Contaminated shower water and clothing may need to be disposed of as "hazardous waste" because they can potentially contain harmful substances or pathogens that pose a risk to human health or the environment. Proper disposal of hazardous waste is necessary to prevent contamination and ensure safety.

Explanation
The statement "The harder the spray, the more effective the eye wash" is false. The effectiveness of an eye wash is not determined by the force or pressure of the spray. In fact, using a high-pressure spray can potentially cause further damage to the eyes. The effectiveness of an eye wash is based on the ability to flush out foreign substances or irritants from the eyes, which can be achieved with a gentle and steady flow of water.
