28:18 Threats to Safety
In a situation where there is a threat to the safety of the Artist or place where the Artist is required to be, by reason of fire, acts of God, acts of the public enemy, and similar causes, the Artist may immediately cease all work and remove him/herself to a place of safety.

28:19 Hazardous Materials
The Theatre will abide by the applicable provincial health and safety legislation with regard to the use of hazardous materials.

Should an Artist develop a medical problem as a result of exposure to said special effect, he/she shall report this matter to the Theatre and shall consult a physician as soon as possible. Upon written advice of the physician to the Theatre, said Artist may cease rehearsing and/or performing.
