Most commercial buildings require ABC dry chemical fire extinguishers (such as Amerex B402 or Badger ADV-550) as a baseline, which cover ordinary combustibles (Class A), flammable liquids (Class B), and electrical fires (Class C). Commercial kitchens additionally require Class K wet chemical extinguishers for cooking oil and grease fires. Server rooms and electrical rooms benefit from CO2 or clean agent (Halotron) extinguishers that won't damage sensitive electronics. The specific types and quantities depend on your building's occupancy classification, square footage, and hazard level per NFPA 10 and your local fire code. RPS Building Specialties can perform a compliance assessment to determine exactly what your building needs.

In California, fire extinguishers require monthly visual inspections (typically performed by the building owner or occupant) and annual professional inspections by a licensed technician holding a valid CSFM (California State Fire Marshal) certificate. The annual inspection includes a 13-point procedure and certification tagging. Additionally, stored-pressure dry chemical extinguishers need a 6-year internal examination and a 12-year hydrostatic test per NFPA 10. OSHA (29 CFR 1910.157) also mandates monthly inspections and annual maintenance for workplace extinguishers. Penalties for non-compliance can reach $16,131 per serious violation.

Surface-mounted cabinets attach directly to the wall surface with the entire cabinet projecting outward 6 to 9 inches. They are the easiest to install and work well on concrete, block, or masonry walls. Recessed cabinets are embedded into the wall cavity so the cabinet sits flush with or slightly protrudes from the wall surface. Semi-recessed cabinets are partially embedded, typically projecting only 2 to 4 inches. The key difference for commercial buildings is ADA compliance: surface-mounted cabinets may violate the 4-inch maximum protrusion rule when mounted between 27 and 80 inches above the floor. RPS specializes in cutting wall openings and framing for recessed and semi-recessed installations to ensure both fire code and ADA compliance.

Yes. OSHA (29 CFR 1910.157) requires that fire extinguishers be clearly visible, accessible, and identified. If an extinguisher is not immediately visible, signage must indicate its location. NFPA 10 further specifies that signs should be installed at eye level and visible from 75 feet. California Title 24 may also require photoluminescent (glow-in-the-dark) signage in certain building types such as high-rises and assembly occupancies. Common signage types include standard wall signs mounted above the extinguisher, projecting flag signs for corridor visibility, vinyl decals for cabinet doors, and floor markings for warehouses and parking structures. RPS supplies and installs all types of fire extinguisher signage to meet OSHA, NFPA, and California requirements.

Absolutely. Tenant improvement (TI) projects are one of the most common times to install or upgrade fire extinguisher cabinets. During a TI, walls are often open or being modified, making it the ideal time to install recessed or semi-recessed cabinets without additional demolition costs. RPS Building Specialties works directly with general contractors and tenant improvement teams to coordinate cabinet installation within the construction schedule. As a building specialties contractor, we handle the complete scope: wall opening cuts, framing, cabinet installation, extinguisher mounting, signage, and initial tagging. This single-source approach eliminates the need to subcontract wall work separately from cabinet installation.
