Substitution & Alternatives Assessment Tool Box
HAZARDOUS CHEMICAL
Substitution
Replacing one entity with another
Informed Substitution• Replacing hazard chemical (chemical of
concern) with safer alternative
• Minimizing unintended consequences . . . . . . .. . . regrettable substitutions
Alternatives Assessment
A process for identifying, comparing and selecting
safer alternatives (chemical & non-chemical)
to replace hazardous chemicals
With the objective of promoting sustainable production & consumption (reducing risk
to humans and the environment)
Alternatives Assessment
• Hazard assessment• Cost & availability• Exposure assessment• Life cycle assessment• Materials management• Performance evaluation• Social impact
