Hydraulic Systems Safety

Quick Facts...

•        Hydraulic systems must store fluid under high pressure.

•        Three kinds of hazards exist: burns from the hot, high pressure spray of fluid; bruises, cuts or abrasions from    flailing hydraulic lines; and injection of fluid into the skin.

•        Safe hydraulic system performance requires general maintenance.

•        Proper coupling of high and low pressure hydraulic components and pressure relief valves are important safety measures.

Hydraulic systems are popular on many types of agricultural equipment because they reduce the need for complex mechanical linkages and allow remote control of numerous operations. Hydraulic systems are used to lift implements, such as plows; to change the position of implement components, such as a combine header or bulldozer blade; to operate remote hydraulic motors; and to assist steering and braking.

To do their work, hydraulic systems must store fluid under high pressure, typically 2,000 pounds or more per square inch. One hazard comes from removing or adjusting components without releasing the pressure. The fluid, under tremendous pressure, is also hot. The worker then is exposed to three kinds of hazards: burns from hot, high-pressure fluid; bruises, cuts or abrasions from flailing hydraulic lines; and injection of fluid into the skin.

Many systems store hydraulic energy in accumulators. These accumulators are designed to store oil under pressure when the hydraulic pump cannot keep up with demand, when the engine is shut down, or when the hydraulic pump malfunctions. Even though the pump may be stopped or an implement disconnected, the system is still under pressure. To work on the system safely, relieve the pressure first. 

Pinhole Leak Injuries

Probably the most common injury associated with hydraulic systems is the result of pinhole leaks in hoses. These leaks are difficult to locate. A person may notice a damp, oily, dirty place near a hydraulic line. Not seeing the leak, the person runs a hand or finger along the line to find it. When the pinhole is reached, the fluid can be injected into the skin as if from a hypodermic syringe.

Immediately after the injection, the person experiences only a slight stinging sensation and may not think much about it. Several hours later, however, the wound begins to throb and severe pain begins. By the time a doctor is seen, it is often too late, and the individual loses a finger or entire arm.

Unfortunately, this kind of accident is not uncommon. To reduce the chances of this type of injury, run a piece of wood or cardboard along the hose (rather than fingers) to detect the leak (see Figure 1).

Improper Coupling

Another hazard is improper coupling of low- and high-pressure hydraulic components. Do not connect a high-pressure pump to a low-pressure system. Do not incorporate a low-pressure component, hose or fitting into a high-pressure system. Component, hose or fitting ruptures are likely to occur.

Pressure relief valves incorporated into the hydraulic system will avoid pressure buildups during use. Keep these valves clean and test them periodically to ensure correct operation.

Maintenance

An improperly maintained hydraulic system can lead to component failures. Safe hydraulic system performance requires general maintenance.

Periodically check for oil leaks and worn hoses.

Keep contaminants from hydraulic oil and replace filters periodically.

Coat cylinder rods with protective lubricants to avoid rusting.

Tips for Safe Operation - Follow these rules for safe hydraulics operation:

•        Always lower the hydraulic working units to the ground before leaving the machine.

•        Park the machinery where children cannot reach it.

•        Block up the working units when you must work on the system while raised; do not rely on the hydraulic lift.

•        Never service the hydraulic system while the machine engine is running unless absolutely necessary       (bleeding the system).

•        Do not remove cylinders until the working units are resting on the ground or securely on safety stands or          blocks; shut off the engine.

•        When transporting the machine, lock the cylinder stops to hold the working units solidly in place.

•        Before disconnecting oil lines, relieve all hydraulic pressure and discharge the accumulator (if used).

•        Be sure all line connections are tight and lines are not damaged; escaping oil under pressure is a fire hazard and can cause personal injury.

•        Some hydraulic pumps and control valves are heavy. Before removing them, provide a means of support such    as a chain hoist, floor jack or blocks.

•        When washing parts, use a nonvolatile cleaning solvent.

•        To ensure control of the unit, keep the hydraulics in proper adjustment.

EXPOSING AN INVISIBLE KILLER

Quick Fact

-Each year in America, carbon monoxide (CO) poisoning claims approximately 480 lives and sends another 15,000 people to hospital emergency rooms for treatment.-

The United States Fire Administration (USFA) and the National Association of Home Builders (NAHB) would like you to know that there are simple steps you can take to protect yourself from deadly carbon monoxide fumes.

 UNDERSTANDING THE RISK

What is carbon monoxide?

Carbon monoxide is an odorless, colorless and toxic gas. Because it is impossible to see, taste or smell the toxic fumes, CO can kill you before you are aware it is in your home. At lower levels of exposure, CO causes mild effects that are often mistaken for the flu. These symptoms include headaches, dizziness, disorientation, nausea and fatigue. The effects of CO exposure can vary greatly from person to person depending on age, overall health and the concentration and length of exposure.

Where does carbon monoxide come from?

CO gas can come from several sources: gas-fired appliances, charcoal grills, wood-burning furnaces or fireplaces and motor vehicles.

Who is at risk?

Everyone is at risk for CO poisoning. Medical experts believe that unborn babies, infants, children, senior citizens and people with heart or lung problems are at even greater risk for CO poisoning.

WHAT ACTIONS DO I TAKE IF MY CARBON MONOXIDE ALARM GOES OFF?

What you need to do if your carbon monoxide alarm goes off depends on whether anyone is feeling ill or not.

If no one is feeling ill:

1. Silence the alarm.

2. Turn off all appliances and sources of combustion (i.e. furnace and fireplace).

 3. Ventilate the house with fresh air by opening doors and windows.

4. Call a qualified professional to investigate the source of the possible CO buildup.

If illness is a factor:
1. Evacuate all occupants immediately.

2. Determine how many occupants are ill and determine their symptoms.

3. Call your local emergency number and when relaying information to the dispatcher, include the number of people feeling ill.

4. Do not re-enter the home without the approval of a fire department representative.

5. Call a qualified professional to repair the source of the CO.

PROTECT YOURSELF AND YOUR FAMILY FROM CO POISONING

n Install at least one UL (Underwriters Laboratories) listed carbon monoxide alarm with an audible warning signal near the sleeping areas and outside individual bedrooms. Carbon monoxide alarms measure levels of CO over time and are designed to sound an alarm before an average, healthy adult would experience symptoms. It is very possible that you may not be experiencing symptoms when you hear the alarm. This does not mean that CO is not present.

n Have a qualified professional check all fuel burning appliances, furnaces, venting and chimney systems at least once a year.

n Never use your range or oven to help heat your home and never use a charcoal grill or hibachi in your home or garage.

n Never keep a car running in a garage. Even if the garage doors are open, normal circulation will not provide enough fresh air to reliably prevent a dangerous buildup of CO.

n When purchasing an existing home, have a qualified technician evaluate the integrity of the heating and cooking systems, as well as the sealed spaces between the garage and house. The presence of a carbon monoxide alarm in your home can save your life in the event of CO buildup.

Heat / Sun Protection

Warmer weather is here, and we should be aware of the risks posed by Heat Exhaustion and Heat Stroke. Especially in young children.

Heat Exhaustion

What happens to the body?

Headaches, dizziness, or light-headedness, weakness, mood changes, irritability or confusion, feeling sick to your stomach, vomiting, fainting, decreased and dark-colored urine, and pale, clammy skin.

First Aid Measures:

• Move the person to a cool, shaded area.
• Don’t leave the person alone. 
• If the person is dizzy or light-headed, lay him/her on their back and raise their legs about 6-8 inches. If the person is sick to their stomach, lay them on their side. Loosen and remove heavy clothing. Have the person drink some cool water (a small cup every 15 minutes) if they are not feeling sick to their stomach. 
• Try to cool the person by fanning them. Cool the skin with a cool spray mist of water or wet cloth. If the person does not feel better in a few minutes dial 911.

(If heat exhaustion is not treated, the illness may advance to heat stroke.)

Heat Stroke

What happens to the body?

Dry, pale skin (no sweating); hot, red skin (looks like a sunburn); mood changes; irritability, confusion, and not making any sense; seizures and collapse (will not respond).

First Aid Measures:

• Call 911 – this is a medical emergency! 
• Move the person to a cool, shaded area. Don’t leave the person alone. Lay them on their back and if the person is having seizures, remove close objects that could cause injury to the person. If the person is sick to their stomach lay them on their left side. 
• Remove heavy outer clothing. 
• Have the person drink some cool water – no caffeine (a small cup every 15 minutes) if they are alert and do not feel sick to their stomach. Do not give liquids if the person has diminished mental status. Immediately cool the person with any means possible. Cool the skin with a spray mist of water, sponge with cold water, apply ice bags or cold packs beside the neck, armpits, and groin.

Lifting Without Overexertion

Lifting Without Overexertion

Overexertion injuries – which most often occur when a load is being lifted or otherwise handled – accounted for 22 percent of nonfatal workplace injuries in 2009, according to data from the Bureau of Labor Statistics. Further, 42 percent of sprains, strains and tears in the workplace stemmed from overexertion – many of them from lifting. To prevent such injuries, NIOSH recommends both administrative controls and worker training.

Administrative controls to reduce overexertion injuries include:

• Plan the workflow to avoid unnecessary lifts, or minimize the distances loads must be carried.
• Tag all heavy or unstable loads. Reduce the weight by putting fewer items in a container or using smaller or lighter-weight containers.
• Pack contents of containers so the weight is evenly distributed.
• Position pallet loads at heights that allow workers to lift from their power zone – above the knees, below the shoulders and close to the body. Avoid storing materials on the floor.
• Rotate workers between lifting and non-lifting tasks. Allow periodic breaks to ensure workers have adequate rest.

NIOSH recommends workers take the following measures to avoid overexertion injuries when lifting:

• Always use mechanical lift devices, when available.
• Before lifting, check the load for stability and weight.
• Lift only as much as you can safely handle on your own. If required, make several trips carrying lighter weight.
• Keep the lifts in your power zone.
• Use your legs to lift the load rather than your back or upper body.
• Use smooth, even motions to avoid jerking.
• Step to the side when you need to turn – do not twist your body.

Try to alternate physically demanding tasks with less demanding ones.

One-Minute Car Safety Seat Check-up

Using a car safety seat correctly makes a big difference. Even the "safest" seat may not protect your child in a crash unless it is used correctly. So take a minute to check to be sure...

Does Your Car Have a Passenger Air Bag?

• An infant in a rear-facing seat should NEVER be placed in the front seat of a vehicle that has a passenger air bag.
• The safest place for all children to ride is in the back seat.
• If an older child must ride in the front seat, move the vehicle seat as far back as possible, buckle the child properly, and make sure he stays in the proper position at all times.

Is Your Child Facing the Right Way for Weight, Height and Age?

• Infants should ride facing the back of the car until they have reached at least 1 year of age AND weigh at least 20 pounds.
• A child who weighs 20 pounds or exceeds the height limit for the car safety seat before he reaches 1 year of age should continue to ride rear-facing in a car safety seat approved for use at higher weights and heights in the rear-facing position.
• A child who weighs more than 20 pounds AND is older than 1 year of age may face forward. It is safest for a child to ride rear-facing until she reaches the top weight or height allowed by the seat for use in the rear-facing position.
• Once your child faces forward, she should remain in a car safety seat with a full harness until she reaches the top weight or height allowed by the seat. When changing the seat for use in the forward-facing position, you must make adjustments. Check your car safety seat instructions.

Is the Harness Snug; Does It Stay on Your Child's Shoulders?

• Harnesses should fit snugly against your child's body. Check the car safety seat instructions on how to adjust the straps.
• The chest clip should be placed at armpit level to keep the harness straps on the shoulders.

Has Your Child Grown Too Tall or Reached the Top Weight Limit for the Forward-Facing Seat?

• Children are best protected in a car safety seat with a full harness until they reach the top weight or height limit of the car safety seat.
• Once your child outgrows his car safety seat, use a belt-positioning booster seat to help protect him until he is big enough to use a seat belt properly. A belt-positioning booster seat is used with a lap and shoulder belt.
• Shield boosters: Although boosters with shields may meet current Federal Motor Vehicle Safety Standards for use by children who weigh 30 to 40 pounds, on the basis of current published peer-reviewed literature, the American Academy of Pediatrics (AAP) does not recommend their use.
• A seat belt fits properly when the shoulder belt crosses the chest, the lap belt is low and snug across the thighs, and the child is tall enough so that when he sits against the vehicle seat back, his legs bend at the knees and his feet hang down.

Does the Car Safety Seat Fit Correctly in Your Vehicle?

• Not all car safety seats fit in all vehicles.
• When the car safety seat is installed, be sure it does not move side-to-side or toward the front of the car.
• Read the section on car safety seats in the owner's manual for your car.
