Hydroblaster Safety High-pressure water cleaning has become more common over the past few years, often replacing the need for sand blasting. The uses of hydroblasters vary from paint and grease removal, tank cleaning and log debarking, to rodding of heat exchangers and cleaning of sidewalks. Although hydroblasters are fairly simple to operate, they can be dangerous if not properly used. A pump is used to increase the water pressure to 10,000 psi, with larger units capable of 45,000 psi or more. This pressurized water is pumped through a flexible steel braided hose and discharged through a pipe called a lance which has...

Time to Chock and Block Those Tires! “I am only going to leave the truck for a minute – it won’t go anywhere.” This is what we hear all the time, but every year, workers are severely or fatally injured because the wheels of a truck or trailer were not chocked. Vehicle drivers are also injured when trailers overturn because unblocked freight shifted during travel. When wheels aren't meant to roll. Accidents are caused each year when a truck or trailer rolls away from the dock because no one took time to chock the wheels. In some cases, drivers were crushed by...

That Container Only Looks Empty! Containers that have held flammable or combustible liquids can remain explosive even after the liquid has been removed. The liquid in the container is replaced by air which mixes with the hazardous vapors. This combination can be explosively ignited by a spark or heat. In fact, these containers are normally more explosive than a full container. How many times have you seen a 5 gallon pail or a 55 gallon drum being used as a welding or grinding stand? This is very dangerous. Any sparks produced could ignite the vapors. Also, the torch flame, heating the container,...

The Dangers of Oily Rags Oily rags left in a closed container can become a safety nightmare. Many people do not believe it can happen. For no apparent reason, fire erupts, usually during off hours – as the materials have had time to react. It is called spontaneous ignition, and preventing is part of your job. Spontaneous ignition occurs when a combustible object is heated to its ignition temperature by a chemical reaction involving the oxygen in the air around us. This “oxidation “ process creates heat that, if not dissipated, will bui8ld up until ignition occurs. Generally, this can happen when...

Excavations Are Serious Business Excavations and trenches need not be deep or large to create a life threatening hazard. Soil is heavy, and failures take place with little or no notice. You can be trapped before there is time to react. So it is important that every excavation be prepared correctly, allowing you to complete your job safely and efficiently. Remember that every trench is different. Soil type, moisture content, depth, configuration, proximity to existing structures, and location of spoil piles all work together to make every excavation unique. Keep these points in mind when working: Follow the recommendations of your...

Front-End Loader If you operate a front-end loader, you have probably experienced the bouncing, weaving, and "road walk" that leaves you feeling as if you are not in total control of the equipment. Hopefully, you have recognized this as dangerous and have learned to slow down, especially when traveling downgrade, when empty, or when traveling on particularly bad terrain. There are other hazards to be considered as well: (1) getting caught in the pinch points of the bucket arms or the pivot area of an articulated machine, (2) collision, (3) running over a pedestrian, (4) spilling a load on others, (5) machine...

Trying To Do The Job Alone Dear Sir. I am responding to your request for additional information regarding how my recent injury occurred. In block number 3 of your accident report form I put trying to do the job alone as the cause of my accident. You said in your letter that I should explain more fully. I trust that the following details will be sufficient. I am a bricklayer by trade. On the day of the accident, I was working alone on the roof of a new six story building. When I completed my work I discovered that I had about 500...

Dangers of Powerline Contact Each year, workers are killed by electrocution from contact with overhead power lines. Over 90 percent of the contacts involved overhead distribution lines. These are the same lines that run in the alleys behind our houses and through our job sites. Since they are so common to us, they seem harmless. This serious mistake is fueled by two common misconceptions: the belief that some overhead lines don't carry enough power to kill, and the belief that power lines are well-insulated. Both are dead wrong. The leading category of contact involves heavy equipment--cranes, drilling rigs, concrete pumps, aerial buckets,...

Hand Tool Safety Hammers, wrenches, chisels, pliers, screwdrivers, and other hand tools are often underrated as sources of potential danger. Hand tools may look harmless, but they are the cause of many injuries. In fact, an estimated 8 percent of all workplace compensable injuries are caused by incidents associated with hand tools. These injuries can be serious, including loss of fingers or eyesight. Hand tools can cause many types of injuries: Cuts, abrasions, amputations, and punctures. If hand tools are designed to cut or move metal and wood, remember what a single slip can do to fragile human flesh. Repetitive motion injuries....
