- Globally Harmonized System for Hazard Communication The Globally Harmonized System includes criteria for the classification of health, physical and environmental hazards, as well as specifying what information should be included on labels of hazardous chemicals as well as safety data sheets.
- Right to Know Law and Workers Rights Most states have their own Right-to-Know laws that cover public-sector workers. In some of these states, workers have stronger rights than under the federal Hazard Communication Standard.
- Material Safety Data Sheets (MSDS) Workers have the right to review the MSDS. Right-to-know laws require that workers have access to an MSDS for each hazardous chemical in their work area during their shift.
- How to Read an MSDS Material Safety Data Sheets (MSDS) are an important requirement of the OSHA Hazard Communication Standard. MSDS have become important documents to inform employees, students, and the general public about how materials can be safely handled, used, and stored.
- OSHA Workers Rights Handbook This publication provides a general overview of worker rights under the Occupational Safety and Health Act (OSH Act).
- Material Safety Data Sheet Quiz This quiz contains seven parts. In each section you will read some background material about OSHA-required content, consult an MSDS sheet, and then answer a few questions.
- Fire Safety
- Flammability limit Mixtures of dispersed combustible materials (such as gaseous or vaporised fuels, and some dusts) and air will burn only if the fuel concentration lies within well-defined lower and upper bounds determined experimentally, referred to as flammability limits or explosive limits.
- Flash Points Explained Flash point is the lowest temperature at which a liquid can form an ignitable mixture in air near the surface of the liquid. The lower the flash point, the easier it is to ignite the material.
- Fire Safety and Prevention Tips Fire in the workplace can be a very dangerous and terrifying experience. Anyone who doesn't know what to do in the event of a fire is not only a danger to themselves but also everyone around them.
- Electrical Fires Fire investigators tend to blame fires on that which they understand least, and that is electricity.

- What About Manholes? Manholes, besides the uncomfortable name, create a unique circumstance, both from an electrical standpoint as well as the confined space issues they create for the worker.
- Confined Spaces: Deadly Spaces This four part video is designed for municipal workers and illustrates the basic rules for working in confined spaces. Oxygen deficiency and other potential dangers are covered. In addition, the health effects and physical characteristics of toxic gases including carbon monoxide, hydrogen sulphide, and methane are examined.

- Electrical testing safety Placing electrical equipment or systems in an electrically-safe work condition might seem simple, but there are several factors to consider.
- Understanding Non Contact Voltage Testers There is considerable confusion regarding the use of non-contact voltage detectors.
- A million and one uses for voltage detectors Voltage detectors are a quick, inexpensive way to check for the presence of live voltage on ac circuits, switches and outlets before working on them. Also known as voltage wands, sticks, "power sniffers" or pens, they clip into a shirt pocket and beep or glow when they detect voltage on exposed conducting parts or through insulation.
- Voltage Detection and Discharge: Similar equipment, different function Two indispensable pieces of equipment when working around medium- and high-voltage lines are voltage detectors and discharge sticks. They look similar and are sometimes confused but have distinct functions that complement (not replace) each other.
