Physical Hazards in Construction
Physical hazards are different types of energy which may be hazardous to construction workers. They include noise, vibration, temperature extremes, and radiation.
This module will take a closer look at these hazards and how to protect yourself.
Noise Hazards
Prolonged exposure to excessive noise levels can cause noise-induced hearing loss. Noise levels at or above 85 decibels can potentially cause hearing loss over time.
When you are exposed to excessive noise levels, the first stage is temporary hearing loss. Over time, the hearing loss becomes permanent.
Several factors influence the noise levels that workers are exposed to. For example, the type of equipment being operated, condition and maintenance of the equipment, and enclosed or partially enclosed spaces.
High noise levels can also be sporadic on construction sites. Damage to your hearing is cumulative and exposure limits are based on 8-hour averages. Workers who are not operating equipment are often also exposed to the excessive noise at the site.
