A work box cutter is a drill attachment that cuts square or rectangular openings in drywall for the installation of outlets, light switches, and low voltage mud rings.
Hazard Analysis — Silica
Problem:
Workers that install and maintain fixtures, lights, motors and pumps may face hazards from silica.Risk Description:
Inhaling crystalline silica can lead to serious, sometimes fatal illnesses including silicosis, lung cancer, tuberculosis, and chronic obstructive pulmonary disease (COPD). When workers breathe in dust containing silica the lung tissue reacts by developing fibrotic nodules and scarring around the trapped silica particles. This fibrotic condition of the lung is called silicosis. If the nodules become too large, breathing becomes difficult and death may result. Silicosis may develop after very short periods of high exposure, but more commonly it develops after many years of lower levels of exposure. There is no cure for silicosis.
Assessment Info:
Work Safely with Silica” at www.silica-safe.org provides information needed to assess the risk, determine if a material contains silica, and an on-line tool to create a job hazard analysis and plan for controlling exposures.
