Our Hands at Work
The hand is the part of the body most often injured and these injuries are sometimes difficult to heal. Hand injuries are preventable. By identifying hazards and developing safety measures, you and your employer can prevent your hands from being among the 500,000 injured in Canada every year.
Think of your hands as …Valuable
Your hands are superbly designed tools of amazing strength and dexterity. They can pinch, grasp, twist, lift, hold and manipulate while doing a wide variety of other specific tasks.
Your hands and wrists are a complex system of bones, muscles and tendons, ligaments, blood vessels and nerves protected by layers of skin. A total of 27 hand and wrist bones are connected to the muscles by tendons. Ligaments join bones together and hold the joints in place. Blood vessels supply nourishment to all these parts. Nerves convey sensations and help to control hand and finger movements.
The skin provides a barrier against chemicals, heat and cold. Skin on the back of the hand is thin and elastic and, on the palm, it is thick to provide traction, cushioning and insulation.
Remember! Your hands are valuable but also vulnerable! If even a small cut makes it difficult and painful to work or play, imagine if you had a serious injury.
Workplace hazards and injury prevention
A hazard is any energy that can cause harm. Injuries can be immediate or may happen over time. In the workplace, your hands are subjected to many hazards.
There are numerous mechanical hazards from tools, equipment, machines, structures and vehicles:
- chains, gears, rollers, wheels and transmission belts;
- spiked or jagged tools;
- edges that catch and tear;
- cutting, chopping and grinding mechanisms;
- cutting tools such as knives and presses;
- falling objects, etc.
A few prevention tips
Work at your own pace. The frequency of hand injuries is proportional to how quickly you work.
- Stay alert! Always watch what your hands are doing.
- Use a push stick to feed a circular saw or other power tools such as jointers and shapers.
- Know how to handle the tools and equipment you work with. Don’t take shortcuts.
- Wrenches should properly fit nuts and bolts.
- Use long magnetic poles for retrieving items from places where it is dangerous for hands to go.
- Presses and other machines should be designed to keep hands away from the work area.
- Control panels should be designed, installed and guarded to reduce the risk of accidents as much as possible.
- Use different colors, shapes or sizes to distinguish safety shut-off controls from all other controls.
- Never start repair work on power tools or machinery without first checking that the power is shut off and the machine is locked out.
- If you are taking any drugs or medication, consult your doctor. Some drugs and medication impair your faculties, prevent you from thinking clearly and slow your reflexes.
Note: It is dangerous to wear rings at work. Even a ring that fits your finger perfectly poses a hazard. If the ring is forced off or breaks, it may pull the flesh from the finger or amputate it. Remember, too, that long hair, loose clothing, dangling accessories, jewellery and similar items can get caught in machinery. If these are worn, they must be tied, covered or otherwise secured to prevent them from becoming a safety hazard.
Advice for protecting your hands
- Your hands must be protected against the hazards of the particular job.
- Gloves should not be worn around machines with moving parts that could catch them and pull the hands into danger areas, for example, machines with pulleys or power-driven machines with rotating shafts.
- Protective sleeves should be long enough to leave no gap between the gloves and the sleeves.
- Do not wear gloves with metal parts when working near electrical equipment.
Some situations call for protection other than gloves. Find out if you would be better protected with barrier creams, finger guards or cots, hand protectors or leather products, arm protectors, sleeves or wristlets.
Things to consider
Too often we forget just how amazing and vulnerable hands really are. Routinely working with a tool or machine can sometimes result in carelessness. Stay alert and work safely.
Remember that an injury can happen in a split second and result in a lifetime of disablement and hardship for you and your family.
