Name two common finishing hazards on a job site and how to mitigate them.

• A. Noise and dust—use masks; Heat exposure—limit outdoor work.
• B. Slips/trips—keep work areas clean and dry; hand-arm vibration—limit use time of vibrating tools and use anti-vibration handles.
• C. Electrical hazards only;
• D. Heat extremes only.

Answer: (B)

Two common finishing hazards on a concrete job site are slips and trips, and hand-arm vibration. Slips and trips happen when the work area is wet, muddy, oily, or cluttered with cords and tools. Keeping surfaces clean and dry directly reduces the chance of someone losing footing during finishing activities like screeding and troweling. It also helps to organize cords, hoses, and equipment so they don’t create trip hazards, and to wear slip-resistant footwear and good lighting so footing is predictable.

Hand-arm vibration comes from using vibrating power tools such as trowels, power vibrators, or grinders. Prolonged vibration can lead to discomfort and long-term health effects. Limiting exposure by reducing how long a worker uses vibrating tools, rotating tasks to share the load, and choosing anti-vibration handles or attachments, along with maintaining tools so they vibrate less, are practical ways to mitigate this risk.

The other options either address hazards less commonly tied to finishing work or omit practical, effective mitigations.
