Workplace hazards: types, computers, office equipment and stress

Hello students, welcome to Kwickprep. An office looks safe, with chairs, computers and air conditioning. But a loose wire or a wet floor can hurt someone in seconds. Today we will learn workplace hazards, hazards from computers, safe use of office equipment, stress at work, and a simple safety checklist.

First, three words we will use again and again. A hazard is anything that can cause harm, like a wire lying across the floor. Risk is the chance that the harm will actually happen. An accident is an unplanned event that causes injury or damage. Every workplace has hazards, even a quiet office, so we must learn to spot them early.

Workplace hazards are usually grouped into four types. Physical hazards come from the space around us, like a wet floor or boxes in a corridor. Electrical hazards come from wires, plugs and machines. Fire hazards are things that can start or spread a fire. Health hazards harm the body slowly, like bad posture, dust or poor ventilation.

Let us look at physical hazards more closely. A wet or uneven floor can make a person slip. Bags, boxes and cables in a walkway make people trip and fall. A heavy file kept on a high shelf can fall on someone's head. Open drawers and sharp table corners cause cuts and bruises. Keep floors dry and walkways clear.

Electrical hazards can give a shock or start a fire. Damaged wires with the copper showing are very dangerous. Putting too many plugs into one socket or extension board overloads it and heats the wires. Never touch a switch or plug with wet hands. And keep your water bottle or tea cup away from computers and sockets.

A fire hazard is anything that can start a fire or make it worse. Overloaded sockets and short circuits cause many office fires. Paper, cartons and cleaning chemicals catch fire easily when kept near heaters. Smoking or lighting a lamp indoors adds an open flame. Blocked fire exits and missing fire extinguishers turn a small fire into a disaster.

Health hazards do not hurt at once, but they damage health over time. Poor air flow, dust and dim lighting cause headaches and allergies. Sitting for long hours without a break hurts the back and neck. Loud noise from machines can damage hearing. Unclean washrooms and shared food can spread germs and illness.

Computers bring their own hazards. Staring at a screen for hours dries the eyes and causes eye strain. Slouching in the chair gives back and neck pain. Typing and using a mouse for hours can cause repetitive strain injury. This means pain in the wrists and fingers from repeating one movement. Faulty cables can also give an electric shock.

Here are simple habits to stay safe at the computer. Keep the top of the screen at or just below your eye level. Keep the screen about an arm's length away. Sit straight with your feet flat and your back supported by the chair. Follow the twenty twenty twenty rule: every twenty minutes, look at something twenty feet away for twenty seconds. And stand up to stretch at least once an hour.

Office equipment includes printers, photocopiers, shredders and projectors. Read the manual before using any new machine. Switch it off and unplug it before you clean or move it. Never open the cover to repair it yourself, because parts inside can be hot or live. Report any fault to the right person and stop using it. When lifting a heavy box, bend your knees and keep your back straight.

Let us test what you learned. The office printer jams, and a sheet is stuck inside. The printer is still switched on and feels hot. What should you do first? Switch it off, unplug it and let it cool, then follow the manual or call the person in charge.

Not every hazard is a wire or a wet floor. Stress is the pressure a person feels when the demands on them seem too high. Common causes are tight deadlines, too much work and conflicts with colleagues. Signs of stress include headaches, poor sleep, anger and trouble concentrating. A stressed worker makes more mistakes, so stress also leads to accidents.

The good news is that stress can be managed. Plan your day and finish the most important tasks first. Take short breaks and eat meals on time. Exercise, sleep well and practise slow, deep breathing when you feel tense. If the pressure does not go away, talk to a senior, a friend or a counsellor.

When you spot a hazard, follow these steps. First ask, can the hazard be removed completely, like picking up a cable from the floor? If yes, remove it. If no, guard it or warn people, for example with a wet floor sign. Then report it to your supervisor so it is fixed properly. Finally, check the area again regularly.

A safety checklist is a list of things to check regularly, so nothing is forgotten. Check that floors are dry and exits are clear and unlocked. Check wires and sockets for damage and overloading. Check that fire extinguishers are in place and ready. Check that the first aid box is stocked and easy to find. Finally, check that your own screen and chair are set correctly.

Let us revise what we learned today. A hazard is anything that can cause harm. Hazards are physical, electrical, fire or health hazards. Computers can cause eye strain, back pain and wrist pain, so follow the twenty twenty twenty rule. With office equipment, read the manual and unplug before cleaning. And manage stress, and use a safety checklist every day.
