    Other Construction Health Hazards

    Course Overview

    Other Constructions Hazards is an intermediate online safety course covering Laser Safety, Lead in Construction and Silica Hazard awareness.

    ‘Laser’ is an abbreviation for Light Amplification by Stimulated Emission of Radiation. Lasers are used in scientific research, chemistry, medicine (eye and other surgeries), industrial use (cutting and welding), commercial (supermarket checkout scanners), military (angles and distances) and construction (angles, boundaries and elevations). Laser light is very useful in construction, but can be a hazard as it can focus a high-energy light beam onto a small focused area. It is important to know how to work with this tool safely.

    Pure lead is a heavy metal and a basic chemical element that can combine with other substances to form lead compounds. Lead paint is a major exposure source that is hazardous when it is chipping or cracking, and is dangerous if disturbed in working areas without controls. You will learn how to work safely with lead in all forms.

    Silica is SIO2 (silicon dioxide) found in rock, stone, cement, concrete and sand. Silica dust is generated by construction activities including cutting, grinding, sanding, brushing, and abrasive blasting. Inhaling this dust can be hazardous. Exposure to silica dust can cause an incurable disease called silicosis. Over 300 people die each year from silicosis.

    Intended Audience

    This online safety course is intended to benefit all construction workers and management employees who may work with or around lasers, lead or silica dust.

    • Construction Workers
    • Construction Foremen
    • Construction Supervisors

    Learning Objectives

    In this Other Construction Health Hazards online course, you will learn the basics of laser hazards and how to control them. If you work with lasers or come into contact with lasers, talk with the operators or review the manufacturer’s safety information. You will learn safe work practices around workplace lead exposures. Lead is toxic and can be absorbed by inhalation, ingestion or skin penetration. Inhaling airborne lead is the biggest source of occupational exposure. This course focuses on the sources of lead, sources of exposure, exposure limits and controlling your exposure to lead. You will also be taught how to anticipate, recognize, evaluate and control silica dust hazards.
