Chemical Safety & SDS Knowledge Flashcards

What is the correct action when a chemical is accidentally spilled on the skin?

Answer: Rinse the affected skin with large amounts of water and check the SDS for further guidance

Copious water rinsing dilutes and removes the chemical; the SDS specifies any additional first-aid steps specific to that substance.

Which chemical should NEVER be mixed with bleach because it produces toxic chlorine gas?

Answer: Vinegar or other acids

Mixing bleach with acids like vinegar releases chlorine gas, which is highly toxic and can cause serious lung damage.

How should a cleaning technician respond when encountering a chemical product they are unfamiliar with at a client's home?

Answer: Do not use it without reading the label and SDS, or use an approved substitute

Using an unknown chemical without reviewing its safety information exposes both the technician and client's property to unpredictable hazards.

What does the term 'dwell time' refer to on a disinfectant product label?

Answer: The minimum amount of time the product must remain wet on a surface to kill specified pathogens

Dwell time is the critical contact period required for the disinfectant's active ingredients to destroy targeted microorganisms.

Why is proper ventilation important when using solvent-based or strong chemical cleaners indoors?

Answer: To disperse fumes and prevent dangerous vapor buildup that could cause health problems or ignition

Vapor accumulation from solvents can reach toxic or flammable concentrations in enclosed spaces without adequate airflow.

A technician should report a chemical spill that exceeds their training level because:

Answer: Large or hazardous spills may require specialized containment to protect health and environment

Hazardous spills beyond a technician's training require professional response to prevent health harm and environmental contamination.
