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.

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...

What You Need To Know About Welding & Cutting Protecting yourself when performing welding operations depends on your understanding of the hazards involved and the proper way to control them. Control of welding hazards includes avoiding eye injury, respiratory protection, ventilation of the work area, protective clothing and having safe equipment to use. Eye hazards include exposure to ultraviolet and infrared light. Welders and their helpers should wear filter glasses with shades ranging from 2 to 14, depending on the type of welding being done, to protect their eyes. Unless a welding arc is behind a screen, not only the welder, but...

Working Safely With Lead It used to be thought that only children were exposed to lead poisoning hazards which occurred mostly from eating lead based paint chips from doors or windows in the home. This is no longer the case. Studies conducted over the past few years now suggest many adults are exposed to lead in the work place and suffer from varying degrees of lead poisoning. These studies have also shown that eating lead based paint chips is not the only or even the primary way for lead to enter the body. Workers that use lead based paints, or work with...

Cumulative Trauma Disorders How Can You Prevent Them? Cumulative Trauma Disorders (CTD's) are strains that may result from long-term repetitive motion or from continually working in an awkward position. Strains commonly occur in the wrists, arms, shoulders or back, affecting the body's joints and surrounding muscles and tendons. CTD's are said to be today's fastest growing occupational problem, affecting all types of employees, from computer operators to construction workers. Modern equipment, tools and machinery have increased production capabilities in many ways. But in some cases, they have also increased the potential for strain injuries in people. These disorders not only cause great discomfort,...

Unexpected Hazards In Demolition Work Remodeling of buildings sometimes involves demolishing parts of existing structures to make room for new improvements. Demolition can expose workers to dangerous materials that are sometimes difficult to recognize. In many cases, even the building owner may not know these hazards are present. Potentially dangerous materials include lead, silica and asbestos. Lead dust is caused by removing, grinding, or cutting materials covered with lead based paint, or from handling metallic lead. Lead fumes can also be created when a torch is used to cut tanks that have contained leaded gasoline or other lead containing products. Since lead...

Ladders Injuries in the workplace because of ladder are commonplace. Falls from ladders can be as painful as a fall from a roof; about a third of all reported falls are falls from ladders. Many of the fall related injuries result from the improper use or the use of a defective ladder. Step/extension ladders are made to access/egress upper levels, not to be used as work platforms. There are specifically designed ladders for use as work platforms such as order pickers. These ladders are constructed with a small platform and guardrail. The following safe work rules should be observed when working...

Forklift Fatalities OSHA estimates forklift fatalities account for 85 fatal accidents per year; 34,900 accidents result in serious injury; and 61,800 are classified as non-serious. According to the Industrial Truck Association, there are about 855,900 forklifts in the U.S. Therefore, over 11% of all forklifts will be involved in some type of accident each year (assuming only one accident per forklift). The ITA also reports that the useful life of a lift truck is about 8 years. This means that about 90% of all forklifts will be involved in some type of accident during their useful life--again assuming only one accident per...

Signaling Techniques Proper signaling can greatly increase the efficiency and productivity of a construction project whether it is guiding a delivery vehicle, a forklift or a crane. Improper signaling can kill or injure workers as well as cause severe property damage on a project. The following points are recommended discussion points when discussing signaling. Guide for Discussion Know the signals. If you have to, get with the operator and coordinate what signals mean. Allow only one person to give signals. Be sure the operator knows who the signal person is. The signal person must: Always be in a position to see both the operator and...
