How to build a safety program for a countertop fabrication shop
The hazards in a stone shop, the written programs OSHA expects, PPE by task, slab handling rules, training, audits and injury records, in one plan a small shop can run.
, CEO, Stonify
A shop safety program is a short set of written plans, routines and records that keeps people from being hurt by the four big hazards in a stone shop: silica dust, heavy slabs, cutting machines and noise. Under federal OSHA rules a typical fabrication shop needs a written silica exposure control plan, hazard communication, lockout/tagout procedures, a PPE hazard assessment, a respiratory protection program if respirators are required, hearing conservation if noise averages 85 dBA or more, forklift and crane training, and usually an emergency action plan. Make one person responsible, train every worker before they touch a machine, walk the floor daily and audit monthly or quarterly. Report a death to OSHA within 8 hours and an in-patient hospitalization, amputation or eye loss within 24 hours.
This article covers the whole program. The silica rule has its own detailed guide in OSHA silica compliance. State plans can require more, so check yours. California is the main example: Cal/OSHA's silica standard (Title 8, Section 5204) and the SB 20 law, in force since January 1, 2026, require wet methods for high-exposure work on artificial stone and a yearly training attestation to Cal/OSHA from July 1, 2026. A proposed Cal/OSHA emergency ban on artificial stone above 1% crystalline silica was awaiting a Standards Board vote as of October 3, 2026. See silica and silicosis.
What can hurt people in a stone shop
Start by being honest about the hazards. In rough order of how badly they hurt people:
Hazard | Where it happens | What goes wrong |
|---|---|---|
Respirable crystalline silica | Cutting, grinding, polishing, cleanup, dried slurry | Silicosis, lung cancer, kidney disease. Slow, permanent, and the main long-term killer in the trade. |
Falling or tipping slabs | Unloading containers and trucks, breaking bundles, pulling slabs from A-frames | Crushing injuries and deaths. A full 3cm granite slab weighs roughly 1,000 lb. |
Lifting and carrying | Moving cut pieces, loading trucks, installs | Back, shoulder and knee injuries, among the most common lost-time injuries |
Machine contact | Saw blades, CNC spindles, edge polishers, waterjets, hand grinders | Amputations, deep cuts, high-pressure water injection |
Sharp stone | Handling raw edges and broken pieces | Lacerations |
Noise | Saws, CNC, hand grinding | Permanent hearing loss |
Electricity and water | Wet machines, cords on wet floors | Shock and electrocution |
Wet floors | Everywhere near wet cutting | Slips and falls |
Flying particles and splash | Grinding, polishing, core drilling | Eye injuries |
Chemicals | Epoxy and polyester adhesives, acetone, sealers, cleaners | Skin and eye burns, sensitization, fire |
Forklifts and cranes | Yard and shop | Struck-by and crushing injuries |
Silica gets the most attention because it is regulated in detail and its damage is permanent. Slab handling deserves just as much attention, because it can kill in a second.
The written programs OSHA expects
These are the federal general industry standards that most often apply to a fabrication shop. Some apply only when a condition is met.
Program | Standard | When it applies | What it needs |
|---|---|---|---|
Silica exposure control plan | 29 CFR 1910.1053 | Any shop cutting stone | Tasks, controls per task, housekeeping; reviewed yearly |
Hazard communication | 1910.1200 | Any hazardous chemical, including stone dust, adhesives and solvents | Written program, safety data sheets (SDS) for every product, labels, training |
Respiratory protection | 1910.134 | When respirators are required | Written program, medical evaluation, annual fit test, training |
Hearing conservation | 1910.95 | Noise at or above 85 dBA as an 8-hour average | Noise monitoring, annual hearing tests, protectors, training |
Lockout/tagout (control of hazardous energy) | 1910.147 | Servicing machines where unexpected startup could injure | Written program, machine-specific procedures, training, yearly inspection of procedures |
PPE hazard assessment | 1910.132 | All shops | Written, signed certification of the assessment; employer pays for required PPE |
Emergency action plan | 1910.38 | When another standard requires one; smart for all shops | Written if more than 10 employees; can be oral for 10 or fewer |
Powered industrial trucks (forklifts) | 1910.178 | Any forklift use | Training, evaluation, re-evaluation at least every 3 years |
Overhead and gantry cranes | 1910.179 | Shop cranes and hoists | Regular inspections by use; trained operators |
Machine guarding | 1910.212 | All machines | Guards on points of operation, nip points and rotating parts |
Injury and illness records | 29 CFR 1904 | Most employers with more than 10 employees | OSHA 300 log, 301 reports, 300A summary |
Two dates to watch in 2026. OSHA revised the hazard communication standard in 2024, and under the compliance dates extended on January 15, 2026, employers must update workplace labels, the written program and training for newly identified hazards in single-substance products by November 20, 2026 (mixtures follow by May 19, 2028). For penalties assessed after January 15, 2026, OSHA's maximums are $16,550 per serious violation and $165,514 per willful or repeated violation, the same amounts as in 2025.
Keep all of these in one binder or folder with one owner. A small shop does not need a consultant to write them. OSHA's small business publications, the Natural Stone Institute and your workers' comp carrier all provide templates. What matters is that the plan matches what really happens on your floor.
Slab handling
Slabs are the hazard new hires underestimate. A standard 3cm granite slab weighs about 17 to 19 lb per sq ft, so roughly 1,000 lb for a full slab, and engineered quartz is only slightly lighter at about 14 to 16 lb per sq ft. A slab that starts to tip cannot be stopped by hand.
Rules that prevent crushing injuries:
Never stand on the downhill side of a leaning slab or between a slab and a rack, wall or truck.
Unload containers and bundles with a written procedure. Secure the remaining slabs before cutting any strap or removing any brace, because a bundle can shift the moment its strap is cut.
Store slabs on rated A-frames or slab racks, leaned a few degrees off vertical as the rack maker specifies, never dead vertical and never unsupported. Load double-sided A-frames evenly.
Do not mix thin and thick slabs on the same side of a rack, where a heavy slab can slide and pinch a thin one.
Keep the yard lit, level and clear. Paint pedestrian lanes away from forklift routes, size forklift aisles for the truck and its load, and keep exit routes at least 28 inches wide, OSHA's minimum.
Lifting equipment:
Use vacuum lifters, slab clamps and cranes for full slabs. Check vacuum lifters before every use: gauge reading, pads free of cracks, battery or pump working, low-vacuum alarm on. Stay within the rated load and follow the maker's manual and ASME B30.20 for below-the-hook lifting devices.
Forklift operators must be trained and evaluated, with re-evaluation at least every 3 years or after an incident.
Inspect cranes, hoists, chains and slings on schedule and tag out anything damaged.
Manual handling of cut pieces:
Carry pieces on edge, not flat. A flat piece flexes and snaps, especially at a sink cutout.
NIOSH's lifting equation starts from a maximum of 51 lb for one person under ideal conditions and reduces it for reach, height, twisting and frequency. Most countertop pieces are far above that, so plan team lifts or equipment.
A common shop rule is two people for small pieces, three or more for large pieces or anything with a sink cutout, and a lifter or cart beyond that. One person calls the lift.
Storage layout is covered in slab storage and yard, and delivery and install handling in handling, transport and lifting.
Machine safety
Guards stay on. Blade guards on saws, enclosures and interlocks on CNC routers and waterjets, spindle and splash guards on edge polishers, and tool rests and tongue guards set correctly on bench grinders.
Emergency stops within reach at every machine. Test them on a schedule, monthly is common.
Lock out before reaching in. Changing a blade, clearing a jam or cleaning a CNC bed is servicing work. Shut off and lock out electrical, hydraulic, pneumatic and water pressure energy using the machine's written procedure.
Waterjets run at tens of thousands of psi. The stream can inject water and abrasive through skin with a wound that looks minor and is a medical emergency.
Hand grinders cause many shop injuries. Use the right guard and wheel for the speed, keep both hands on the tool, and never remove a guard to reach a tight spot.
Noise
Bridge saws, CNC routers and especially hand grinding commonly run above 90 dBA at the operator.
8-hour average | OSHA requirement (1910.95) |
|---|---|
85 dBA (action level) | Hearing conservation program: monitoring, baseline and annual hearing tests, hearing protectors available, training |
90 dBA (PEL) | Engineering or administrative controls where feasible; hearing protectors required |
95 dBA | Allowed for no more than 4 hours without protection |
100 dBA | 2 hours |
105 dBA | 1 hour |
Real-world protection from earplugs and muffs is often about half the label NRR (noise reduction rating), so pick protectors that workers will actually wear all shift. For hand grinding, many shops use plugs and muffs together.
Wet floors, electricity and chemicals
Floors. OSHA requires floors to be kept dry where feasible, and where wet processes are used, drainage must be maintained and dry standing places such as platforms or mats provided where feasible. Trench drains, squeegees and slip-resistant boots are the practical answer.
Electricity. Have an electrician wire and ground wet machines. Use GFCI protection where the electrical code requires it around water. Keep cords off wet floors and inspect them.
Chemicals. Keep an SDS for every adhesive, sealer, solvent and cleaner. Store flammables such as acetone in approved containers away from ignition sources. Wear nitrile gloves and eye protection when mixing epoxy or polyester adhesives. Provide an eyewash where anyone handles corrosive products.
PPE by task
PPE is the last layer of protection, after engineering controls and safe work practices. The employer must assess the hazards in writing and pay for required PPE, with narrow exceptions such as ordinary safety-toe boots that workers may wear off the job.
Task | Eyes and face | Hands | Feet | Hearing | Respiratory |
|---|---|---|---|---|---|
Slab handling, unloading | Safety glasses | Cut-resistant gloves (ANSI/ISEA 105 level A4 or higher) | Safety-toe boots | As needed | Not usually |
Bridge saw or sawjet (wet) | Safety glasses | Waterproof or cut-resistant | Safety-toe, slip-resistant | Yes | Per exposure assessment |
CNC operation | Safety glasses | As needed | Safety-toe, slip-resistant | Yes | Per exposure assessment |
Hand grinding and polishing (wet) | Goggles plus face shield | Cut-resistant, waterproof | Safety-toe, slip-resistant | Yes, often double | Often required; per assessment |
Mixing adhesives, sealing | Safety glasses or goggles | Nitrile | Safety-toe | No | Per SDS |
Cleanup of slurry and dust | Safety glasses | Waterproof | Slip-resistant | No | Per assessment |
Which respirator, if any, depends on your air sampling and on the silica rule. See OSHA silica compliance. In California, Section 5204 generally requires powered air-purifying respirators (PAPRs) with an assigned protection factor of 1,000 for high-exposure tasks on artificial stone and on natural stone above 10% crystalline silica, with narrow exceptions when monitoring shows exposures below the action level.
Training workers
Train before exposure, not after an incident. A practical onboarding sequence for a new shop hire:
Before the first day on the floor. Shop rules, emergency exits and assembly point, reporting injuries and near misses, SDS location, and the silica basics: why the shop cuts wet, never dry-sweeps and never uses compressed air on dust.
Before using any machine. Machine-specific training, lockout/tagout procedure, guards and e-stops, hearing protection, and a supervised run until the trainer signs off.
Before handling slabs. Rack and bundle rules, vacuum lifter checks, team-lift calls, and forklift or crane training for anyone who will operate them.
Before wearing a required respirator. Medical evaluation, fit test and respirator training.
Ongoing. Short toolbox talks weekly or every two weeks, annual refreshers on silica, hazard communication and hearing, and retraining when a task, material or machine changes.
Train in a language each worker understands, and have them show the skill, not just sign a sheet. OSHA's silica rule requires workers to demonstrate knowledge of the hazards and controls. The OSHA/NIOSH countertop silica hazard alert, updated in February 2026 and available in English and Spanish, makes a good handout. In California, SB 20 adds a yearly written attestation to Cal/OSHA, starting July 1, 2026, that workers doing high-exposure tasks on artificial stone have been trained. Record the date, topic, trainer and each attendee. For the broader hiring and training plan, see hiring and training.
Audits and inspections
A program stays real only if someone checks it. A cadence that works for small shops:
Check | Who | How often | What to look at |
|---|---|---|---|
Walk-through | Shift lead | Daily, 10 to 15 minutes | Water flowing at every tool, guards on, floors and aisles clear, slabs secured, lifter checks done |
Spot audit | Shop manager | Monthly | PPE in use, SDS current, extinguishers and eyewash, cords, rack condition, housekeeping |
Full audit | Owner or outside consultant | Quarterly or at least yearly | Every written program, training records, air sampling and medical surveillance status, injury log trends |
Incident review | Manager and people involved | After every injury or near miss | Root cause and the fix, not blame |
Grade findings simply: fix now for anything that could kill or seriously injure (a missing guard, a dry-cutting grinder, an unsecured slab), and fix within a week for the rest. Track open items to closure.
OSHA's On-Site Consultation Program will do a free, confidential audit for small businesses. Consultants do not issue citations, but you must agree to fix serious hazards they find. Your workers' comp carrier may also offer free loss-control visits.
Injury reporting and records
Report to OSHA a work-related death within 8 hours, and an in-patient hospitalization, amputation or loss of an eye within 24 hours, by phone (1-800-321-OSHA) or online.
OSHA 300 log. Most employers with more than 10 employees must record work-related injuries and illnesses, post the 300A summary from February 1 to April 30 each year, and keep logs for 5 years. Many manufacturing establishments with 20 or more employees must also submit their 300A data electronically by March 2 each year, and larger ones must submit more detail. Check OSHA's Injury Tracking Application for your requirements.
Near misses. Not required, but the cheapest lessons you will ever get. Make reporting easy and never punish it.
Injury history drives your workers' comp experience modification rate (EMR), which multiplies your premium for about three years. A clean record also helps win commercial work, where general contractors ask for EMR and safety programs. See insurance and risk.
Beyond the shop: trucks and job sites
Delivery and installation carry their own hazards. Secure slabs on rated A-frame racks with enough straps: federal cargo securement rules for commercial vehicles require tie-downs with a combined working load limit of at least half the cargo weight. On site, the construction standards apply, including the construction silica rule for any cutting or grinding. Keep site cutting to a minimum, and use a shrouded grinder with a HEPA vacuum when you must. See handling, transport and lifting.
Common mistakes
A binder no one reads. A plan written for an inspector but not for the crew protects no one.
Buying PPE instead of fixing the process. Respirators and gloves do not replace water at the tool, guards on the machine and equipment for lifting.
Letting speed win. Dry "touch-up" grinding, skipped lifter checks and one-person carries happen when the schedule is tight. Build safety time into the production plan.
No owner. Every item needs a name next to it.
Forgetting the installers. Install crews face the same silica and lifting hazards with less supervision.
FAQ
Who in a small shop should run the safety program? One person with authority to stop work, often the shop manager or owner. They do not need a safety degree, but they need time on the schedule and backing to enforce the rules.
Do we need a written emergency action plan with 8 employees? If a standard requires an emergency action plan, one with 10 or fewer employees may communicate it orally. Writing a one-page plan with exits, meeting point and who calls 911 is still worth doing.
Are cut-resistant gloves safe around grinders and saws? They protect against sharp stone edges but will not stop a spinning blade or wheel, and gloves can be caught by rotating parts. Follow the tool maker's guidance for each machine.
How often should respirators be fit tested? Before first use, at least every 12 months, and whenever the worker changes respirator model or has facial changes that could affect the seal.
Does OSHA require safety training records? Several standards require proof that training happened, such as forklift certification and the silica rule's training requirement, and inspectors will ask for it. Keep dated sign-in sheets with topics and trainers for every session.
Can the shop require workers to buy their own boots? OSHA lets employers not pay for ordinary safety-toe footwear that workers can wear off the job. Specialty footwear and other required PPE must be provided at no cost.
