Factory Mutual
4 insurance companies
provides engineering and inspection services
develops standards and conducts fire research
National Building Code

they stimulate the burning process and may cause an explosion
National Fire code
provides technical requirements for an acceptable level of safety within a community and minimum fire safety requirements
technical organization that develops, publishes and distributes consensus standards
Two main types of smoke detector
combustion products (ionization)
photoelectric (linear beam, projected beam)
