What does SDS stand for in the context of cleaning chemicals?
Answer: Safety Data Sheet
An SDS (Safety Data Sheet) provides comprehensive hazard, handling, storage, and emergency information for chemical products.
Which section of an SDS provides first-aid measures in case of accidental chemical exposure?
Answer: Section 4 – First-Aid Measures
Section 4 of the SDS is standardized to cover first-aid procedures for inhalation, skin contact, eye contact, and ingestion.
What is the danger of mixing bleach (sodium hypochlorite) with ammonia-based cleaners?
Answer: It produces toxic chloramine gas that can cause serious respiratory harm
Bleach and ammonia react to form chloramine gases, which are toxic to the respiratory system even in small concentrations.
When a cleaning chemical splashes into a technician's eyes, the immediate first step is to:
Answer: Flush the eyes with clean water for at least 15 minutes and seek medical attention
Continuous flushing for at least 15 minutes dilutes and removes the chemical to minimize tissue damage.
Dilution ratios on cleaning product labels are important because:
Answer: Using too much product wastes money and can leave harmful residues or damage surfaces
Over-concentration wastes product, may damage surfaces, and can leave chemical residues that pose health or safety risks.
What type of personal protective equipment (PPE) should be worn when handling concentrated acids or alkaline degreasers?
Answer: Chemical-resistant gloves and eye protection at minimum
Concentrated acids and strong alkalis cause chemical burns on skin and eyes; gloves and eye protection are the minimum required PPE.
