Preventing eye, skin & lung damage

By Nick Warrick

Metalworking is integral to many industrial processes, such as manufacturing, construction, maintenance and automotive repair. Metalworking trades play a skilled role but are exposed to higher than average levels of occupational health and safety hazards. Working with metals exposes workers to potentially serious injuries and long-term health risks. Metal shards can cause permanent eye injuries or blindness; toxic dust and fumes pose a danger to the lungs if inhaled, and the high temperatures that are often involved in metalworking can cause severe burns and skin damage.

Protecting metal workers from these hazards requires constant vigilance and the use of personal protective equipment (PPE) on the site or shop floor. Training in safe operating procedures is also crucial so that employees always follow these procedures. Although there are many potential dangers to health and safety in the metalworking industry, it is possible to manage these risks effectively, and this article will outline the common hazards and proven strategies to help keep workers safe.

Identifying Risks

Some of the significant health and safety hazards associated with metalworking include:

• High temperatures. There is a severe risk of fire and burning caused by open flames, hot materials and sparks.
• Combustible metal dust. Metal dust in the air can explode or ignite in certain circumstances, causing severe injuries.
• Fumes and gasses. Welding can produce toxic fumes and gases that contain harmful compounds that can cause serious lung damage and illnesses when inhaled over prolonged periods.
• Injury. Metal workers are at high risk of injury from handling sharp metal and hot metal debris. Cuts and eye injuries are common.
• Hand injuries from handling metal materials are the most common among metalworkers. Sharp metal edges and metalworking tools can easily slice or puncture the unprotected skin on the hands.
• Eye injuries are the next most common among metalworkers. Flying metal fragments or debris kicked up by machinery can easily cause damage to unprotected eyes.
• Lung damage is another common problem for metalworkers. Inhaling metal dust particles can cause them to penetrate deep into the lungs, causing severe damage with prolonged exposure. Iron dust can lead to siderosis — “welder’s lung” — while cobalt, chromium and nickel dust have been linked to chronic obstructive pulmonary disease. In addition, fumes from welding contain fine and ultrafine particles that can reach the distal airways in the lungs, increasing the risk of respiratory diseases such as lung cancer, asthma and pneumonia. Stainless steel welding fumes are particularly dangerous and are classified as Group 1 carcinogens by the IARC (International Agency for Research on Cancer).

Essential Safety Tips

There are several ways the workplace can be made safer for metalworkers:

Wear cut-resistant gloves when handling sharp metal pieces, and use face shields, goggles, leather aprons and other Personal Protective Equipment (PPE) as required for specific metalworking tasks. Also, ensure no loose clothing or jewelry is worn as they could get caught in machinery.

Keeping the workplace clutter-free helps prevent tripping and falling, and ensures easy access to fire extinguishers and first aid kits. When cleaning metal debris, use brushes or vacuum cleaners — never compressed air.

Maintain all equipment to the manufacturer’s specifications and ensure machines are never operated without safety guards or shields.
