Final answer:
Chemical protective gloves are made from various materials and are crucial for safety but are not effective against all chemicals, requiring glove selection based on the chemicals being handled.
Step-by-step explanation:
Regarding which statement is true about chemical protective gloves, option 2 is correct: they are not effective against all chemicals.
Chemical protective gloves are indeed made of various rubber and synthetic materials, such as polybutadiene, polychloroprene, and styrene-butadiene rubber. However, no glove material can provide complete protection from all chemicals.
Therefore, it is essential to select the appropriate type of glove depending on the specific chemicals being handled to ensure effective protection.
Using the right gloves is part of a broader safety approach that may include full body suits and masks when handling hazardous substances like chlorine.
It's important to note that gloves, while essential, are part of a safety system that includes hand washing after removing gloves to ensure no chemical residue harms the skin.
Disposal of hazardous materials must be conducted according to provided instructions to minimize the risk of exposure and environmental contamination.
