Locking In Safety…

Understanding and implementing OSHA-approved safety measures

Last year the Occupational Safety and Health Administration (OSHA) issued more than $750,000 in citations to the metal fabrication industry for equipment-related safety violations. This includes tool usage and guarding issues, control of hazardous energy (lockout/tagout), and electrical safety. These citations do not begin to account for the total cost to metal fabricating shops when considering associated property damage, medical costs, workers’ compensation and insurance increases, lost work time, and lawsuits that often go along with the citations. To avoid equipment-related incidents, you must understand OSHA requirements and have safety programs in place, including those pertaining to tool safety and machine guarding, lockout/tagout, and electricity.

Tool Safety and Machine Guardingmachineguards

Safe tool usage and machine guarding violations were the most frequent and costly citation areas last year. The first thing that you must do is assess the specific hazards by evaluating each piece of equipment. If the machine is new, determine all points of operation, pinch points, and areas that require protection. Ensure that all required guards are in place, and replace any missing guards before allowing anyone to use the equipment.

If you have an older machine that needs guards, you must first determine if the machine is still made. If it is, contact the manufacturer and ask for information on the current guards supplied with new machines. Purchase or replicate the new guard configurations to provide protection, and discard any equipment that cannot be guarded adequately.

After you have assessed the hazards and have adequate guards on your equipment, you can then develop your safety program. Equipment operators must leave the guards on at all times unless the equipment is locked out. Include in your safety program your policy on removal of guards, including who is authorized to do it, and the required lockout/tagout procedures. Also include discipline for employees who remove or bypass guards.

Next, explain the function and purpose of the guards to each employee. Managers and employees must be familiar with the proper guards so they can recognize when something is missing. Without knowledge of the safety program and the purpose and function of the guards that protect them, employees are more likely to bypass or remove them. Remember that a successful training program is always time and money well spent; studies have shown a $4 to $6 return for every dollar invested in safety and health.

Lockout/Tagout Safety

tagoutFailure to follow safe lockout/tagout procedures also accounted for a significant percentage of citation dollars. An effective lockout/tagout program is especially critical because the type of accident it is meant to prevent typically is severe and can result in crushing, amputation, struck-by, or electrocution injuries. OSHA requires you to identify the practices and procedures necessary to shut down and lock out or tag out machines and equipment; provide locks; and train employees on their role in the lockout/tagout program. Also, conduct periodic inspections to maintain or enhance your hazardous energy control program. The No. 1 citation in this area is lack of an effective written program.

Assess hazards by first identifying the lockout requirements for each piece of equipment used, serviced, and maintained at your facility. All energy sources must be documented, including direct and hidden sources. Documentation must include the hazard posed, the magnitude of danger, any special or unusual conditions, and the correct isolation methods and required devices.

About 95 percent of all lockout/tagout citations involve companies’ failure to have a formal program in place. The energy control or lockout/tagout program must be written and must include your hazard assessment, devices to be used, personnel authorized to perform lockout/tagout, enforcement policy and training methods, and the method for auditing and updating procedures. You must develop written procedures for shutting down and locking out each machine. Except in emergencies, each lock/tag must be removed by the person who put it on, and each employee must have his or her own locks and tags. Make sure your written program accounts for situations when servicing lasts longer than one shift, when contractors are involved, or when a group of employees services a piece of equipment.

The training program must consist of effective initial training and periodic retraining. You must have certification that training has been given to all employees covered by the standard. The training each employee needs is based on the relationship of his or her job to the machine or equipment being locked or tagged out. OSHA identifies three types of employees: authorized, affected, and other.

1. Authorized employees are those responsible for implementing the energy control procedures to perform service and maintenance. They must understand the need for lockout/tagout procedures and be able to recognize hazardous energy sources. They also must have a clear understanding of the means and methods of controlling the various types of energy sources and how to verify that each energy isolation is effective.
2. Affected employees are those who operate or use equipment on which servicing or maintenance is being performed under lockout, or those who work in an area where servicing or maintenance is performed. Affected employees must ensure that they can recognize when a lockout/tagout procedure is being implemented. The goal of this training is simple: Whenever there is a lockout or tagout device in place on an energy-isolating device, the affected employee must leave it alone and make no attempt to operate the equipment.
3. All other employees must be able to recognize when the control procedure is being implemented and understand that they must leave lockout/tagout devices alone and not attempt to energize or operate the equipment.

site-meetingRetraining must be provided whenever there is a change in job assignments, machines, equipment, or processes that present a new hazard; when there is a change in energy control procedures; inadequacies are present in employees’ use of the energy control procedure; or at least every three years.

Periodic inspections must be performed annually on each energy control procedure at your site, and the employer must certify that the periodic inspections have been performed. The certification must identify the particular machine, the date of the inspection, the employees included in the inspection, and the name of the person performing the inspection.

Electrical Safety

An average of one worker dies from electrocution on the job every day. Even low-voltage or low-current shock can cause serious harm or death. All of the equipment in a metal fabricating shop operates on 110 V or more and is capable of causing electric shock, burns, or electrocution.

Check your tools and equipment to ensure that the ground prong is present and that cords are in good condition. OSHA requires that live parts of electrical equipment operating at 50 V or more be guarded against accidental contact. Whenever conduit or electrical equipment is in a location where it could be exposed to physical damage, it must be enclosed or guarded. Junction boxes, pull boxes, and fittings must have approved covers. Unused openings in cabinets, boxes, and fittings must be closed.

Flexible cords are vulnerable because they can be damaged by aging, door or window edge contact, staples or fastenings used to hold them in place, abrasion from adjacent materials that they may contact, and various activities in their proximity. Improper use of flexible cords or use of damaged cords can cause shocks, burns, or fire. Whenever possible, use one of OSHA’s recognized hard-wiring methods. OSHA allows flexible cords to be used only for certain applications.

Check your circuits regularly. An inexpensive tester can tell you if the ground iselectrical-6 connected and can also test your ground fault interrupter (GFI) protection. Your safety program must include policies for grounding systems and electrical shutoff device systems. Develop policies for use of ladders and scaffolding around electrical devices. Extension cords have specific current ratings that must not be exceeded or they can overheat and cause a fire without tripping the circuit breaker. Use a qualified electrician for installation and repair of circuits.

Personnel who are at primary risk of electrical hazards are arc welders, those who work with or around electric power tools and equipment, and maintenance and janitorial staff who are responsible for handling electrical issues at your facility. At lesser risk are all other personnel who work with or around other electrical equipment, including lighting, computers, coffee makers, and so forth. Training must be adequate to the needs of each employee depending on his or her specific tasks.

Employees must understand the built-in safety features of electrical systems, including insulation, ground fault circuit interrupters, double-insulated devices, grounding (both of the circuit and the equipment), guarding of live electrical parts, and fuses and circuit breakers.

Employees also must follow safe work practices, such as de-energizing electrical equipment before inspecting or making repairs, correct usage of flexible cords and extension cords, recognition of damaged electric tools and procedures to remove them from use, how to work safely near energized lines, and use of personal protective equipment.

All lockout/tagout devices (locks and tags) must have four key characteristics:

* They must be durable, meaning that they must withstand the environment for the length of the expected exposure.
* They must be standardized according to color, shape, or size.
* Devices must be substantial enough to minimize early or accidental removal.
* They must be identifiable, clearly identifying the person who applied them and warning of hazards should the machine or equipment become energized.

Keep on Truckin’…Operating and maintaining a forklift truck safely

Operating and maintaining a forklift truck safely:

The use of fork trucks to handle and store materials and products efficiently is vital to the metal fabricating industry. Unfortunately, unsafe fork truck use often results in injuries, property damage, and costly Occupational Safety and Health Administration (OSHA) citations. Each year tens of thousands of injuries related to forklifts occur in U.S. workplaces. Most incidents also involve property damage.

The majority of fork truck accidents can be attributed to lack of safe operating procedures and safety rule enforcement and insufficient or inadequate training. In addition to training and education, applying general safety principles—such as proper work practices, equipment, and controls—can help to reduce such workplace accidents.

Cost of Unsafe Fork Truck Usageforklift

The powered industrial trucks (PIT) standard (29 CFR 1910.178) is one of the most commonly cited standards in the materials handling industry. According to the U.S. Department of Labor, OSHA forklift violations alone cost the manufacturing industry almost $1 million last year, with metal fabricating businesses accounting for the largest amount—approximately $250,000. This is the cost of OSHA citations only, it does not account for the cost of property damage, lost work time, replacement of an injured employee, medical expenses, increased workers’ compensation rates, and potential lawsuits.

Safe Operation

All new PITs, except vehicles for earthmoving and over-the-road hauling, must meet the design and construction requirements established in the American National Standard for Powered Industrial Trucks, Part II, ANSI B56.1-1969.

Each of the 11 different designations of industrial trucks is suitable for use in certain locations and under specific conditions. Pay special attention to work areas containing hazardous concentrations of chemicals or metal dusts. Special requirements for trucks in these areas include safeguards to prevent ignition of vapors, fumes, or dust, such as completely enclosed electric motors and electrical equipment and strict temperature limitation features. Also, mechanical operator protection becomes especially important where loads can shift or fall. To protect operators in this situation, ensure that trucks, especially high-lift riders, have an overhead guard if possible, and make sure that fork trucks have the manufacturer’s vertical load backrest extension.

Aisles, Passageways, and Docks. Aisles and passageways must have sufficient clearance at loading docks, through doorways, and wherever turns must be made. Providing sufficient clearance for mechanically moved materials can prevent workers from being pinned between the equipment and fixtures in the workplace, such as walls, racks, posts, and other machines. Sufficient clearance also helps prevent the load from striking an obstruction and causing materials to fall on or injure an employee.

Make sure that all passageways that workers use remain clear of obstructions and tripping hazards. Do not store materials in aisles or passageways, and mark permanent aisles and passageways appropriately.

Modifications. You are allowed to modify a powered industrial truck only with the manufacturer’s written approval. In this case, you also must change the plates, tags, and decals that list capacity, operation, and maintenance instructions to reflect the new information. Appropriate training also must be provided.

If the truck is equipped with front-end attachments that aren’t factory-installed, make sure the truck is labeled to identify these attachments and show the truck’s approximate weight—including the installed attachment—when it’s at maximum elevation with its load laterally centered. Extended forks move the load away from the operator and can move the center of gravity off the base, causing the entire truck to become unstable and tip. Alternate or modified equipment requires careful consideration of load limits.

forklift_accident_with_bombStability. According to OSHA, forklift overturns are the leading cause of fatalities involving forklifts; they represent about 25 percent of all forklift-related deaths. To maintain stability:

* Center the load on the forks as close as possible to the mast to pull in the center of gravity and minimize the potential for the truck tipping or the load falling.
* Do not overload a lift truck; this impairs control and can cause it to tip.
* Do not place extra weight on the rear of a counterbalanced forklift to allow an overload without the manufacturer’s approval.
* Carry the load in the lowest position possible when traveling.
* Pile and cross-tier all stacked loads correctly to prevent slippage and load shift.
* Secure dock boards or bridge plates properly so they won’t shift when equipment moves over them.
* Refuse to handle an unstable or unsafely arranged load.

Loading and Unloading.
Preplan and train employees on how to move loads and what the limits are. The forklift2size, weight, and shape of the material being moved will dictate the type of equipment used. All material handling equipment has rated capacities that determine the maximum weight the equipment can safely handle and the conditions under which it can handle that weight. The rated capacity must be displayed on each piece of equipment and cannot be exceeded except for load testing.

Before loading or unloading, prevent movement of trucks, trailers, or railroad cars by ensuring that brakes are set and wheels are chocked. It is recommended that truck keys be removed to prevent unintentional “driving off.”

Load Stacking
. Stacking materials can be dangerous if workers don’t follow safety guidelines. Falling materials and collapsing loads can crush or pin workers, causing injuries or death. To prevent injuries when stacking materials:

* Ensure that stacks are stable and self-supporting.
* To avoid creating a hazard to passersby when removing supplies, do not store pipes and bars in racks that face main aisles.
* Stack and block poles, as well as structural steel, barstock, and other cylindrical materials, to prevent spreading or tilting unless they are in racks.
* Consider placing bound materials on racks, secured by stacking, blocking, or interlocking, to prevent them from sliding, falling, or collapsing.

Ensure that employees can identify safe stacking heights easily: Paint walls or posts with stripes to indicate maximum stacking heights for quick reference. Be sure to enforce any rules you have on height limitations when stacking materials.

Fuel Safety

Four main fuel types are used to power fork trucks: gasoline, diesel, propane, and electric batteries (produced by the interaction of water and acid). Each fuel type has safety issues, some more than others. Because gasoline is flammable, it should be used outdoors in a nonsmoking area. Safe gasoline storage and dispensing is both an OSHA and an Environmental Protection Agency (EPA) issue. While less flammable, diesel fuel and diesel exhaust contain known carcinogens, and safe handling procedures must be established for them.

Liquefied petroleum (LP) gas, also known as propane, is a derivative of natural gas. Like gasoline, it’s both flammable and explosive. However, it’s also a cryogenic liquid, which means that contact with skin can result in frostbite.

No smoking, open flames, sparks, or electric arcs are permitted near LP tank storage or tank-filling areas. If you fill your own LP tanks, do it outdoors in a well-ventilated area to prevent the buildup of gas vapors. Keep tools and other metallic objects away from LP tanks. Have a charged ABC dry chemical fire extinguisher in filling areas. Ensure that employees understand the proper method of changing an LP tank and the safety precautions to follow. Personal protective equipment (PPE) requirements include safety glasses and rubber or leather gloves.

With electric forklifts, electrical shock is a potential hazard, as is the immense weight of the battery—as much as 1,500 pounds. Because hydrogen gas, a byproduct of the industrial battery’s charging process, is highly flammable, smoking is prohibited near it. Safety shower and eyewash stations must be readily available in case an employee comes into contact with sulfuric acid.

Combustion Exhaust Safety

Gasoline, diesel, and propane are fuels that are burned and emit combustion byproducts. Carbon monoxide is a byproduct of the incomplete combustion of anything containing carbon, including fossil fuels.

OSHA considers carbon monoxide to be one of the most dangerous industrial hazards. Because it’s colorless and odorless at room temperature, it has no warning properties. The most common means of exposure is through inhalation—especially in enclosed spaces. Carbon monoxide concentrations are especially high in the exhaust from internal combustion engines. Forklift operators are on the list of the most typical occupations that may experience this hazard. Control measures include controlling emissions, ventilation, and PPE.

Truck Maintenance

OSHA data has identified key items that can help prevent accidents that occur while maintaining these trucks:

* Ensure that replacement parts on industrial trucks are equivalent to original parts.
* Isolate battery-charging in designated safe areas.
* Provide materials for flushing and neutralizing spilled electrolytes when changing or recharging batteries.
* Vent fumes in the charging area from off-gasing batteries.
* Provide adequate overhead hoists and conveyors to handle the large batteries safely.
* Disconnect the battery before repairing electrical systems.

Training Requirementstestimonial-ad-2

Employers are responsible for training all personnel who work with or around forklifts on potential hazards and safe work practices. OSHA training requirements for operators were enhanced significantly in 1999 because of the high accident rate across the U.S. Today all employers must develop a training program specific to the type of truck to be driven and the working conditions encountered. Employers now must evaluate the operator’s performance in the workplace and certify that each operator has successfully received the training needed.

Refresher training, including an evaluation of each operator’s performance, must be conducted at least every three years. Retraining must be immediate, however, if:

* The operator is observed operating the vehicle in an unsafe manner.
* The operator is involved in an accident or near-miss incident.
* The operator is assigned to drive a different type of truck.
* Conditions in the workplace change that could affect safe operation.

Fork trucks are an essential tool in the metal fabricating industry, so you must ensure that they are an asset, and not a liability, by assessing the work site for potential safety problems, developing safe work procedures, and adequately training employees.
