Vancouver's Best Painters: Safety

SAFETY

Objectives

1. Explain the obligations and responsibilities of workers, employers, and the Occupational Safety and Health Administration (OSHA) with regard to safety.
2. Describe the nature of the hazard(s) and safety rules and guidelines for job site safety relating to:

• Personal hygiene and work clothing
• Personal protective and life saving equipment
• Respiratory hazards
• Fall hazards
• Hazardous chemicals and materials
• Lead hazards
• Asbestos hazards
• Confined space hazards
• Painting tool and equipment hazards
• Hot and cold weather hazards
• Electrical hazards

3. Explain the purpose of Hazardous Communication (HazCom) programs including:

• The elements or parts required of a HazCom program
• The use of Material Safety Data Sheets (MSDSs)
• The use of Hazardous Materials Identification System (HMIS) and National Fire Protection Association (NFPA) codes

Trade Terms Introduction

Acute effects of overexposure: The adverse effects that are normally evident immediately or shortly after a short term period of exposure (seconds, minutes, hours, or days) to a hazardous material without implying a degree of severity.

American National Standards Institute (ANSI): A non-profit organization that has established voluntary standards for the design, testing, and use of various products.

Chronic effects of overexposure: The effects that develop slowly over a long period of time (weeks, months, years) from exposure to a hazardous material without implying a degree of severity.

Flash point (FP): The lowest temperature of a liquid at which it gives off sufficient vapor to form an ignitable mixture with the air near the surface of the liquid or within the container used. Materials with flash points below 100°F (38°C), such as most solvents and solvent-borne coatings, are considered flammable hazards.

Hazardous Materials Identification System (HMIS): A hazard communication system of codes developed by the National Paint and Coatings Association. It uses colors, numbers, letters, and symbols that quickly identify the health hazards, flammability, and reactivity of a material. It also identifies the proper personal protection equipment and other information pertaining to the material.

High-efficiency particulate air (HEPA) filter: A high-efficiency filtering device designed to remove 99.97% of all particles larger than 0.3 micron.

Immediately dangerous to life and health (IDLH): The definition of an atmosphere that poses an immediate hazard to life or produces immediate, irreversible, and debilitating effects on health.

Material Safety Data Sheet (MSDS): A data sheet issued by a manufacturer or producer of material containing information and instructions on the chemical and physical characteristics of a substance, its hazards and risks, safe handling requirements, and actions to be taken in the event of fire, spill, overexposure, etc.

Micron: A unit of measurement equal to one-millionth of a meter or approximately 0.00003937 inch (25 microns equal about 0.001 inch).

National Institute for Occupational Safety and Health (NIOSH): An agency that performs studies, analyzes data, and publishes information, guidelines, and recommendations related to worker health and safety.

Occupational Safety and Health Administration (OSHA): An agency of the U.S. Department of Labor that is responsible for developing and enforcing regulations to support the Occupational Safety and Health act, the federal law designed to protect people from unsafe work environments.

Permissible exposure limit (PEL): The airborne concentration that has been established by OSHA as the enforceable exposure limit. PELs are expressed in parts per million (ppm) or micrograms per cubic meter (mg/m3). Unless otherwise indicated, they are based on time- weighted average (TWA) concentrations for a normal 8-hour workday and a 40-hour workweek.

Short-term exposure limit (STEL): The airborne concentration to which workers can be exposed for up to 15 minutes without suffering ill effects.

Spontaneous combustion: The process of a material catching on fire and burning as a result of the heat generated by internal chemical action.

Threshold limit value (TLV): The airborne concentration of a substance to which a normal, healthy worker may be exposed for eight hours a day, 40 hours a week during a working lifetime without adverse health effects. TLVs are recommended limits established by the American Conference of Governmental Industrial Hygienists (ACGIH). Normally, the TLV represents a time-weighted average (TWA).

Toxic: Poisonous. Any material which can cause illness or injury.
