It is not feasible to eradicate all risks within the work place. It is possible, however, to ensure that workers are provided with appropriate protective head wear. Accident figures suggest that a disturbing number of people sustain head injuries while at work. Many of these injuries are avoidable and could be prevented if hard hats safety was observed.

Safety Laws

Laws governing safety in the work place must be obeyed. Violations of these can result in stiff penalties being imposed, usually in the form of substantial fines. A willful violation could result in a criminal conviction. Arguably, employers also have a moral duty to their employees to protect their health and wellbeing.

Protection

There are specific circumstances that demand safety clothing and equipment should be worn. If there is a possibility that objects may fall from above, or that workers could bump into them, then hats must be worn. If there is a risk of electrocution, from overhead cables for example, the appropriate headgear is an absolute necessity.

Options

Different types of helmet are required in different situations. A risk assessment of the work place should inform the choice of headgear. There are two basic types of helmet. The Type I helmet protects the crown of the head. The Type II helmet protects the crown of the head and protects against side impacts. The inclusion of additional features, such as face shields or ear defenders, is appropriate in some instances.

Electrical Currents

Protective headwear is also categorized into different classes according to the level of protection they afford against electrical currents. Class G, or general class hats, will protect against shocks of up to 2 200 volts. Class E, or electrical class hats, are proof tested at 20 000 volts. Class C refers to conductive hats; these provide no significant protection against electrical currents.

Deterioration

Protective hats are subject to wear and tear. Most manufacturers will recommend that they be replaced every five years. If at any time cracks appear in the shell, or the shiny surface area of the shell becomes dull and scratched, replacement is advisable. A brittle shell is also an indicator that it is no longer fit for the purpose. The suspension, the straps and mounts that attach hats to heads must be renewed if any part of it becomes broken or loose or can no longer be securely fitted.

Maintenance

Workers should avoid making any modifications to their hats as doing so may compromise performance. Similarly, they should avoid using paints, solvents or harsh chemicals on hats. Hats are best stored out of direct sunlight as UV exposure causes deterioration. The straps should never be pulled back over the peak of the helmet. They should always be worn with the peak facing forwards.
