Using Portable Fire Extinguishers In the event of a fire, the correct use of a portable fire extinguisher could mean the difference between suffering a minor loss or a major one. Portable fire extinguishers, if used properly, can make that difference. But there are several things to consider in using fire extinguishers.

CLASSES OF FIRES AND FIRE EXTINGUISHERS: Class A Involves ordinary combustibles such as paper, wood, cloth, rubber or plastics. The common extinguishing media is water or dry chemical. Class B Flammable liquids, grease...

Ventilation Work activity or the presence of harmful substances in industrial environments frequently produces airborne contaminants. These contaminants can be controlled by isolating them from the breathing zone, substitution of a less hazardous substance or process, or by providing adequate ventilation. Ventilation is one of the most common engineering control methods and can be defined as the movement of fresh air into a space in order to replace contaminated air and/or control the temperature in a space. Natural ventilation usually does not provide a sufficient volume of airflow to ventilate enclosed spaces or to promptly remove highly toxic airborne contaminants from breathing...

Unsafe Acts General Safety -  Most of us know that accidents are caused by only two things - unsafe acts or practices, and unsafe conditions. Some of us even know that 9 out of 10 accidents are the result of unsafe acts, or things we do when we know better. This is kind of strange if you think about it. We have more to fear from our own actions than from any other job hazards around us. Why do we deliberately expose ourselves to injury every day? It Won't Happen To Me Basically, most of us are just thinking about getting the job done...

Want A Drug User On Your Work Team? More and more companies require drug testing these days. Chances are your company schedules pre-employment or random drug tests for its employees. Some people don't like the procedure very much. So what's the best possible attitude to have about this matter? You can joke about it, that's okay. You can grumble about it, that's natural. But do you want your employer to change the company policy and stop the testing? Here is what that would probably mean: Firms that do not test these days tend to end up with a greater percentage of...

Knee Pads Construction workers (and especially roofers) are prone to have knee problems. We bend our knees almost as much as we bend our backs and then at the end of the day, complain about our aching bodies. Just as we must be careful in lifting, we must be careful in bending. To assist in saving our bodies, think about using kneepads as an important part of personal protection equipment. Guide for Discussion Do we have exposure to knee injuries? Is there a way to “engineer out” the constant knee bending situations on this job? What are the appropriate times and places to...

Warning: Read The Signs! When is it that people pay the most attention to signs? It seems to be while driving a car! Have you ever wondered why that is? Most likely it's because signs are the simplest way to direct, instruct, and warn people. During your commute to the job site today did you happen to notice all the signs along the way? "You'll need to detour on this road," one tells you. "Slow down, you're driving too fast!" another advises. "Watch out for that bump," you are warned… Road and travel indicators are not the only signs that direct, instruct...

Was It An Accident Or Was It An Error? What is an accident? Briefly, it is a sudden and unforeseen event. Given that definition, can we say that the Apollo fire that killed three astronauts on the launch pad, and the Challenger disaster, were accidents? The first Apollo fatalities were due to a fire that occurred when the spacecraft cabin was charged with pure oxygen during a test. Unfortunately, there was an electrical short under the seat of one of the astronauts. Oxygen fed the resulting fire. The men could not escape because of a poorly designed escape hatch that took too...

Table Saws We all recognize how important our hands are to our employability. However, every year hundreds of fingers and hands are lost to table saws. Table saws are the surest and cleanest way to lose a finger or a hand. Much of this is a result of getting used to operating a table saw and then losing respect for it. That is why it is so important that we review the common safety rules pertaining to the operation of a table saw. Guide for Discussion Two common types of saws:  Table saw; radial arm saw. General Operating Rules: Never operate without all guards...
