Answer:

PPE means any device or appliance designed to be worn or held by an individual for protection against one or more health and safety hazards

Explanation:

The use of PPE always restricts the wearer to some degree.

The psychological effect of PPE may be such that the individual wearing the PPE feels more protected than he or she actually is.The fundamental principle is that personal protective equipment (PPE) should only be used as a last resort.

The safety and health of employees must be first safeguarded by measures to eliminate workplace risks at source, through technical or organisational means (e.g by substituting hazardous chemical ) or by providing protection on a collective basis (e.g providing scaffolding instead of harnesses).

Collective protective measures covering numbers of employees in a workplace must have priority over protective measures applying to individual employees.

If these measures are not sufficient, only then should PPE be used to protect against the hazards that are unavoidable.
