Storing Materials in an Open Yard
Storing materials in an open yard requires attention to combustible materials, access, powerlines, and fire protection.
These materials are being stored in a lumber yard.
- Combustible Materials: Stack combustible materials securely. Stacks or piles must be no more than 16 feet high. Store combustible material at least 10 feet away from a building or structure.
- Access: Driveways between and around combustible storage piles must be at least 15 feet wide. Keep them free from accumulations of material or rubbish. Use a map grid system of 50 by 150 feet when planning driveways in open-yard combustible material storage areas.
- Powerlines: Do not store materials under power lines or where materials may block egress or emergency equipment.
- Fire Protection: Provide portable fire extinguishing equipment rated 2-A:40-B:C at accessible marked locations in the yard so that the nearest extinguisher is no more than 50 feet away for a Class B hazard or 75 feet away for a Class A hazard.
