Injury may result from high temperatures under normal operating conditions, causing:
- Burns due to contact with hot accessible parts
- Degradation of insulation and of safety-critical components
- Ignition of flammable liquids
Examples of measures to reduce risks include:
- Taking steps to avoid high temperature of accessible parts
- Avoiding temperatures above the ignition point of liquids
- Provision of marking to warn USERS where access to hot parts is unavoidable
High temperature warning marking — you may use the following high temperature warning marking:
4. Mechanical hazards
Injury may result from:
- Sharp edges and corners
- Moving parts which have the potential to cause injury
- Equipment instability
- Flying particles from imploding cathode ray tubes and exploding high pressure lamps
Examples of measures to reduce risks include:
- Rounding of sharp edges and corners
-Guarding
- Provision of SAFETY INTERLOCKS
- Providing sufficient stability to free-standing equipment
- Selecting cathode ray tubes and high pressure lamps that are resistant to implosion and explosion
respectively
- Provision of markings to warn USERS where access is unavoidable
5. Radiation
Injury to USERS and to SERVICE PERSONS may result from some forms of radiation emitted by
equipment.
Examples are sonic (acoustic), radio frequency, infra-red, ultraviolet and ionizing radiation, and high intensity
visible and coherent light (lasers).
Examples of measures to reduce risks include:
- Limiting the energy level of potential radiation sources
- Screening radiation sources
- Provision of SAFETY INTERLOCKS
- Provision of markings to warn USERS where exposure to the radiation hazard is unavoidable
