(a)  places life in jeopardy,
(b)  produces unconsciousness,
(c)  results in substantial loss of blood,
(d)  involves the fracture of a leg or arm but not a finger or toe,
(e)  involves the amputation of a leg, arm, hand or foot but not a finger or toe,
(f)  consists of burns to a major portion of the body, or
(g)  causes the loss of sight in an eye; (“gravement blessé”)
2.    Reporting requirements for workplace death or critical injury consolidates sections 51-53 of OSHA, removing previously instated industry specific requirements.3.    In written report or notice of workplace accident employers must include the following information:

  • The name, address and type of business of the employer.

  • the name and address of the legally qualified medical practitioner, registered nurse who holds an extended certificate of registration under the Nursing Act, 1991 or medical facility that is attending to or attended to the worker.
4.    Prescribes specific reporting requirements for mining and construction employers. For construction projects, notice must be provided if the following incidents occur:
