This is a special custom box made specifically for buildings that require a more attractive box. WHMIS boxes are required when you have hazardous materials in the building to supply information to firefighters. These boxes are made from solid stainless steel, are weather resistant, include highly visible reflective lettering and graphics, include common building/room key tags, mounting screws/wall anchors and either (2) stainless steel padlocks or (2) keys depending on locking system required. NOTE: City of Toronto requires Padlocks (AA38PSS), Region of Peel requires Keys for Peel Region (AA38SS). Check with your local Fire Department for locking system requirements. 13"H x 13"W x 4"D
