Physiological age

Physiological (or biological) age is a measure of how well or poorly the body is functioning relative to the chronological age.


PPE, which stands for Personal Protective Equipment means all equipment designed to be worn or held by the worker (clothing, helmets, goggles) to protect him/her against one or more hazards likely to endanger the worker’s safety and health at work, and any addition or accessory designed to meet this objective. The hazards addressed by protective equipment include physical, electrical, heat, chemicals, biohazards, and airborne particulate matter. PPE must be used when the risks cannot be avoided or sufficiently reduced by technical means of collective protection or procedures of work organisation. (Source)

Psychological age

Psychological age is how old one feels, acts and behaves. It is subjective and based on a person’s self-assessment.

Psychosocial risks

Psychosocial risks are those aspects of work design and the organisation and management of work, and their social and environmental context, which may have the potential to cause psychological or physical harm. Issues such as work-related stress, workplace violence and harassment are linked to psychosocial risks. (Source)
