Many elevator companies no longer use which type of solvents because of health risks and fire hazards?

• A. water-based
• B. alcohol-based
• C. petroleum-based
• D. silicone-based

Answer: (C)

Safety and hazard awareness drive solvent choices in elevator maintenance. Petroleum-based solvents are highly flammable and emit toxic fumes that can irritate the eyes and lungs, with longer-term exposure posing more serious health risks. Their lower flash points require strict fire protection and handling measures, making them less desirable. Because of these health and fire concerns, many elevator companies have moved away from petroleum-based solvents in favor of safer options like water-based formulations. Other solvent types may still be used in limited applications, but they generally don’t carry the same combination of acute health risks and fire hazard as petroleum-based ones.
