Monitors and alarms allow early identification and quick response. Effective alarm systems should activate automatically and also be able to be set off manually from clearly identified, accessible activators; use signals distinguishable from other signals and clearly audible across the premises; include a visual component where noise levels or protective clothing could prevent recognition; and keep working if main power fails. They should be installed to the manufacturers' specifications and tested regularly. Fire alarms should be installed where fire control may need large quantities of firefighting water at a fixed installation, with minimum exposure to firefighters, and in consultation with the emergency service where large quantities of chemicals are involved.
