• adhesives are electrically conductive
• vapours may ignite easily
• adhesives weaken steel beams
• adhesives lower oxygen levels

question 21 (1 point)
how many inches are in 5 feet 9 inches?

• 57 inches

Explanation:

Analyze Question 19

Wet mastic contains chemicals and solvents that can cause skin irritation or chemical burns. To prevent direct skin contact, chemical-resistant gloves are required. Kevlar gloves protect against cuts, hearing protection protects ears, and steel-toed boots protect feet.

Analyze Question 20

Solvent-based adhesives release volatile organic compounds (VOCs) into the air. These vapours are highly flammable and can easily ignite if they come into contact with an open flame, spark, or hot surface.
