Free fire escape plan · excavation contractors
Home base for an excavation contractor is a shop where excavators and loaders come in for repair, a parts room stocked with oil and lube, an office, and a yard full of parked machines, trench boxes, pipe and a diesel tank. Turn a graph-paper sketch of the shop and yard, a phone photo or a floor plan into a free draft with exits, routes and a meeting point, then compare it with the yard and job-site steps further down.
This is a draft to check, not a fire inspection or an approval of your fuel tank or your trench work. Federal OSHA or your state plan and the local fire code set the rules, so walk the routes with machines in both bays before the map goes up.
Shop, yard and diesel
Machines roll into the shop for repair, leave for the next job and spend the night in the yard, so what stands between people and the doors changes from week to week. Draw the shop with a machine in every bay, because that’s when the walk to the doors is tightest, and put the yard and the tank on the same map.
OSHA’s exit route rule starts from two: a workplace has at least two exit routes, and a single one is allowed only where everyone could still get out safely given the number of people, the size of the building and how it’s laid out (29 CFR 1910.36(b)). With an excavator in one bay and a loader in the other, the drawing above gives the shop a south door and an east man door.
No materials or equipment may sit in an exit route, whether for good or just for a while (29 CFR 1910.37(a)(3)). A skid steer left against the man door overnight, or a loader parked across the shop aisle while it waits for a part, blocks the way out as surely as a pallet of pipe fittings.
Section 7 of your diesel’s safety data sheet covers handling and storage, including what it has to be kept apart from, and Section 5 covers how a fire involving it is fought (OSHA QuickCard 3493). Then stand the tank and pump well away from every door and from the walk to the meeting point, and ask the fire marshal about tank rules, which come from the local fire code.
| On the site | On the map | Source |
|---|---|---|
| An excavator or a loader in each bay | Draw the machines in, and keep the walk between them and both doors open. | 1910.37(a)(3) |
| Oil and lube drums and used oil | Show the drums; if your crew is expected to use extinguishers on Class B fires, one hangs within 50 feet of travel. | 1910.157(d)(4) |
| The battery charger | Mark the charging spot and keep air moving there, so gas from the batteries can’t build up into an explosive mix. | 1910.305(j)(7) |
| The welding cart | Mark where welding happens; movable things that can burn go somewhere safe first, or guards hold back the heat, sparks and slag. | 1910.252(a)(1) |
| The diesel tank and pump | Draw them where they stand in the yard, clear of every door and of the walk to the meeting point. | Plain planning advice |
A shop with empty bays always looks easy to leave. Walk both routes on a day when an excavator and a loader are inside, the welding cart is out and a bucket or a track is lying on the floor, and move whatever narrows the way to either door.
Before and during the dig
Most of an excavation crew’s day is spent away from the shop, and the emergency that belongs to this trade happens in the ground: a bucket catches a gas line. The plan for that moment is short, and every operator and laborer should know it before the first scoop.
| Do | Don’t | Source |
|---|---|---|
| Walk away from the area at once, upwind if you can | Start a truck or a machine to get away, or drive into a vapor cloud | PHMSA |
| Call 911 once you reach a safe spot, then the pipeline company | Make calls on a phone right next to the leak | PHMSA |
| Tell everyone nearby to clear out too | Go looking for the leak or try to work a pipeline valve | PHMSA |
| Leave a burning gas line to the fire department | Try to put out a natural gas fire yourself | PHMSA |
The posted map covers the shop and the yard, but crews read it on their way out the door. Add a short box beside it: call 811 before every job, and if a line is hit, leave on foot, upwind, and call 911 from a safe spot.
The same calling, marking and careful digging protects electric, water, sewer and telephone lines too, so keep the numbers of the line owners you work around most with the posted plan.
Assembly point · the generator
Use a floor plan, a PDF, a phone photo of a site drawing or a sketch on graph paper. Label the shop, the parts room and the office, draw every man door, and sketch the yard with the tank and the spots where machines park. You get back routes, exits, safety symbols and a meeting point; the bays, the tank and the parking rows are yours to check against them.

What you get is a draft to check, not a finished plan. Walk each route from the bays, the parts room and the office, move anything a machine or a pipe delivery blocks, then post it.
Before and after
The plain plan shows a parts room with shelving and oil and lube drums, an office with a desk and a plan table, and a maintenance shop with an excavator and a wheel loader in the bays, tool chests, a welding cart, used oil drums and a battery charger, beside the equipment yard. The draft adds routes to the front door, the south door and the east man door, exit signs, extinguishers, alarm pulls, first aid and an assembly point out front.

Parking and fueling
By evening the yard fills with excavators, dozers, loaders, skid steers and dump trucks, and the people heading home walk between them. Give the machines rows, give people a walkway, and keep both away from the doors.
The written plan includes how everyone is accounted for once they’re out (1910.38(c)(4)). Crews in a contractor’s yard come and go all day, so keep a daily sign-out board at the office and carry it to the meeting point.
OSHA’s portable extinguisher distances don’t apply to extinguishers provided for use outside buildings, so the one by the pump is a planning choice; ask your fire marshal or insurer what the yard needs.
Shop rules and trench rules
An excavation contractor works under two sets of OSHA rules. Part 1926, the construction standards, applies to employees doing construction work, which OSHA defines as construction, alteration and/or repair (29 CFR 1910.12). Digging a trench for a new line is that kind of work; repairing your own machines in your own shop isn’t named in the definition, so the shop plan in this guide follows the general industry rules in part 1910. Ask OSHA or your state plan if some of your work is hard to place.
For the shop and yard, the emergency action plan is written down and kept at the workplace, though an employer with 10 or fewer employees may share it by word of mouth (29 CFR 1910.38(b)). Go over it with each employee when the plan is first made or they start the job, when their duties under it change and whenever the plan changes (1910.38(f)).
In trench excavations 4 feet deep or more, a stairway, ladder, ramp or other safe means of egress is placed so that nobody has to travel more than 25 feet sideways to reach it (29 CFR 1926.651(c)(2)). That’s the trench’s version of an exit route, and it moves along as the trench grows.
Where too little oxygen (below 19.5 percent) or a hazardous atmosphere exists or could reasonably be expected, such as near a landfill or where hazardous substances are stored close by, the air in an excavation deeper than 4 feet is tested before anyone goes in (1926.651(g)(1)(i)).
| On the job | The rule | Source |
|---|---|---|
| Spoil piles, pipe and machines | Kept at least 2 feet back from the edge of the excavation, held back by retaining devices, or both. | 1926.651(j)(2) |
| A bucket carrying a load | Nobody stands underneath a load being handled by lifting or digging equipment. | 1926.651(e) |
| A dump truck at the excavator | Workers stay clear of any vehicle that is being loaded or unloaded. | 1926.651(e) |
| Fuel used on the job site | Once more than 5 gallons of fuel or other flammable or combustible liquids are in use, an extinguisher rated 10B or higher is kept within 50 feet. | 1926.150(c)(1)(vi) |
| Flammable liquids on site | Kept out of stairways, exits and the areas people normally use to get out safely. | 1926.152(a)(2) |
How to slope, shore or shield a trench is outside this guide, which only covers getting people out and accounted for.

In most shops, yes. OSHA’s general industry rule requires at least two exit routes and permits a single route only where the number of employees, the size of the building and its layout let everyone get out safely (29 CFR 1910.36(b)). With machines filling the bays, give people a second door they can reach without squeezing past them.
Follow PHMSA’s leak advice: leave the area on foot right away, don’t look for the source, get others to leave and stay upwind. Don’t start vehicles or machines, don’t drive into a vapor cloud and don’t try to put out a gas fire. Call 911 from a safe location, then the pipeline company.
PHMSA says digging safely means calling 811 before each job, small ones included, and the call is free. OSHA also requires the estimated location of underground utilities to be determined before an excavation is opened (29 CFR 1926.651(b)(1)). Your state’s law sets how far ahead you must call.
In trench excavations 4 feet deep or more, OSHA requires a stairway, ladder, ramp or other safe way out placed so that no one travels more than 25 feet sideways to reach it (29 CFR 1926.651(c)(2)). Plan where it goes before the crew climbs in, and move it along as the trench grows.
Yes. A sketch on graph paper, a site drawing or a phone photo works if the walls and doors are readable. Draw the shop, every man door, the diesel tank and the parking rows, so the outside routes on the draft are easy to check.
