Flammables, LPG and Anhydrous Ammonia · v1.0.0 · October 23, 2026

Course developed by Todd Jerome Jenkins, MS, CSP.

Recognize chemical and fire hazards. Learn storage, handling, LPG training, ammonia transfer oversight and emergency requirements. Fourteen audible lessons; allow about 40–55 minutes.

Online knowledge component only. Actual chemical, equipment and task instruction, practical verification, respiratory protection and emergency-role training remain separate. Completion does not authorize system design, installation, transfer operations or emergency entry.

1. Identify the material, work and applicable rule

By the end: Identify the actual chemical, activity and applicable requirements before assignment.

Flammable liquids, liquefied petroleum gas (LPG) and anhydrous ammonia need different controls. Start with the product identity, safety data sheet (SDS), work task and equipment. A familiar trade name or container color does not establish what is inside.

General-industry rules include 1910.106 for flammable liquids, 1910.110 for LPG and 1910.111 for covered anhydrous ammonia systems. Construction has separate flammable-liquid and LPG rules in 1926.152 and 1926.153. Do not copy a storage limit or procedure across industries without checking its scope.

The ammonia rule includes refrigerated ammonia storage, but excludes ammonia manufacturing plants and refrigeration plants using ammonia solely as refrigerant. Exclusion from this particular rule does not remove duties under other applicable standards, such as hazard communication or process safety management.

This course is a worker and supervisor knowledge component. It does not qualify someone to design a system, install piping, fill containers, unload a tank car, enter a hazardous atmosphere or perform emergency response. The employer must provide the actual task instruction, controls and verification.

Basis: 29 CFR 1910.106, 1910.110, 1910.111(a); 1926.152, 1926.153

2. Use labels, SDSs and understandable instruction

By the end: Find the correct SDS and explain the task’s hazards and protective actions.

Hazard communication training is required at initial assignment and when a new chemical hazard is introduced into the work area. It must explain detection of a release, physical and health hazards, protective measures, labels, the SDS and the employer’s written program. A folder of SDSs alone is not training.

Locate the product identifier and hazard statements. Use SDS sections on first aid, fire, accidental release, handling, storage, exposure controls and physical properties. Check the actual product and revision; do not use a household-product sheet for a different industrial concentration.

Workers need ready SDS access during the shift and instructions they understand. Ask the worker to explain the warning signs, safe actions and reporting route. Address language, literacy and access needs before exposure. A signed attendance sheet cannot show whether a worker understands the task.

Keep workplace labels intact and use the employer’s compliant labeling system for secondary containers. Do not assume an unlabeled bottle is harmless or identify it by smell. Stop use until the material and controls are verified.

Basis: 29 CFR 1910.1200(h); 1926.59

3. Recognize vapor, ignition and pressure hazards

By the end: Recognize ignition and release hazards without using odor as a clearance test.

A flammable liquid can give off vapor that ignites. Flash point is a test-based measure of when enough vapor can form for ignition; it is not a safe operating temperature or the temperature at which every liquid ignites on its own. Heating a material can change the control needs.

Ignition sources include smoking, open flames, hot surfaces, electrical equipment and sparks from static or mechanical work. A source outside the spill can ignite vapor that travels to it. Keep hot work and nonapproved equipment out of controlled areas under the employer’s procedure.

LPG is stored under pressure and can rapidly release vapor and very cold liquid. A container exposed to fire presents a severe pressure hazard. Ammonia presents serious toxic and corrosive hazards as well as pressure and potential fire hazards; do not treat it as simply another fuel gas.

Odor is not a reliable way to measure a safe concentration. A gas can affect people before they make a safe decision, and the absence of smell is not an all-clear. Use the employer’s required detection, ventilation and release-response arrangements.

Basis: 29 CFR 1910.106(a), (e); 1910.110; product SDS

4. Store flammable liquids in the right containers and places

By the end: Check container approval, quantity, compatibility and clear access against the applicable storage plan.

Use approved containers and storage arrangements suitable for the product, quantity and applicable standard. A container that does not leak today is not necessarily approved for flammable-liquid service. Keep closures intact and report damage, missing identification or incompatible storage.

For covered general-industry cabinet storage, 1910.106(d)(3) limits Category 1, 2 or 3 liquids to 60 gallons and Category 4 liquids to 120 gallons. These figures are not permission to combine maxima or ignore container, room, building or fire-code limits. The employer must verify the full arrangement.

Construction 1926.152 has its own cabinet, quantity and container provisions. Keep liquids out of exits, stairways and normal passage routes. Do not assume a general-industry cabinet calculation alone approves a construction storage location.

Segregate incompatible materials according to the SDS and approved storage plan. Maintain aisles, spill-control arrangements and fire-protection access. If a cabinet is full, obtain an approved storage decision instead of placing extra cans by the door or in an ordinary cupboard.

Basis: 29 CFR 1910.106(d); 1926.152(a)–(c)

5. Control dispensing, static and spills

By the end: Use the verified dispensing arrangement and stop when a required control is missing.

Dispense only under the approved procedure using suitable equipment and ventilation. For covered general-industry dispensing of Category 1 or 2 liquids and Category 3 liquids below a 100 °F flash point, the rule requires electrical interconnection between nozzle and container. Qualified review must define the correct arrangement.

Bonding equalizes electrical potential between conductive objects; grounding connects equipment to ground. A clamp touching paint or an unsuitable surface may not provide the required connection. Do not invent a grounding arrangement for plastic containers or assume a clamp alone controls every ignition source.

Inspect the assigned transfer equipment as instructed. Report damaged hoses, failed ventilation, leaks or missing controls before starting. Follow the actual stopping and spill procedure. Do not bypass a self-closing device or use pressure to force transfer contrary to the applicable rule.

This lesson does not teach a universal transfer sequence. Product properties, equipment design, electrical classification and the workplace determine the safe method. Observe the approved method during separate task instruction and stop if the setup differs from it.

Basis: 29 CFR 1910.106(e)(2), (e)(6); 1926.152(e)

6. Train LPG personnel for their actual functions

By the end: Confirm function-specific training and stay within the employer’s authorized duties.

OSHA requires personnel who install, remove, operate or maintain LPG equipment to be properly trained for that function. Passing a general knowledge course does not establish readiness for each of those different jobs. A trained operator is not automatically an installer or repair technician.

The employer should identify the equipment, assigned duties, manufacturer instructions, inspection points, stopping process and reporting limits. Separate instruction must address the actual connection, exchange or transfer task before it is assigned. Verify understanding and safe performance in a controlled setting.

For covered industrial and bulk installations, an existing standard watch service must include the LPG installation and properly trained personnel. Security observation is not permission to repair a leak. Watch personnel need clear reporting and withdrawal duties.

Retrain when the equipment, task or observed performance shows a gap. This provision does not specify a universal annual LPG course or fixed online duration. Other training requirements can apply, including powered-industrial-truck operator training and transportation requirements.

Basis: 29 CFR 1910.110(b)(16), (d)(12)(i)

7. Protect LPG containers and equipment

By the end: Use suitable protected equipment and report damage or suspected leaks without improvising repairs.

Use approved LPG equipment and the correct container for the service. Keep required markings legible and safety relief devices unobstructed. Never modify a valve, regulator or relief device to make an incompatible connection fit.

Protect containers and piping from vehicle impact, falling objects and unauthorized handling. Follow the specified orientation and support for the actual container; a general rule of thumb cannot replace the manufacturer and installation requirements. Empty containers can still contain hazardous vapor.

Inspect for damage and other abnormalities from a safe position under the employer’s procedure. Do not check a suspected leak with a flame. If a release is suspected, stop affected work, withdraw and report through the site’s emergency process; only trained, assigned personnel may perform permitted checks or shutdowns.

Storage and use have different rules. Do not move spare cylinders indoors merely because an operating appliance is permitted there. The employer must determine the correct storage location, quantity limits, separation and protection under the applicable rule.

Basis: 29 CFR 1910.110(b), (c), (f); 1926.153

8. Apply construction LPG and heating controls

By the end: Keep storage out of buildings and verify actual heater, ventilation and access arrangements.

Construction permits certain LPG uses inside buildings under specific conditions; it does not generally permit indoor storage of LPG. Section 1926.153 prohibits storage within buildings and requires storage locations that do not obstruct exits, stairways or safe egress.

Temporary heating requires suitable equipment, ventilation and protection from combustible materials. Keep heaters stable and use the required clearances and installation instructions for the actual unit. Do not enclose a previously open work area without reassessing ventilation and fuel-gas controls.

Combustion equipment can create carbon monoxide hazards even when the fuel connection is sound. A worker with headache, dizziness or other concerning symptoms needs prompt withdrawal and reporting under the emergency plan. Absence of fuel odor does not prove combustion air is safe.

Coordinate heater locations and deliveries with other trades. Protect hoses and containers from work damage and keep access clear. Only assigned personnel may adjust, service or relocate the setup under the approved procedure. A portable heater is still a controlled piece of equipment.

Basis: 29 CFR 1926.153(h)–(k); 1926.154

9. Recognize ammonia exposure and system hazards

By the end: Recognize toxic, corrosive, cold and pressure hazards and use only approved compatible equipment.

Anhydrous ammonia contains no water as supplied. It can injure the eyes, skin and respiratory tract. Liquid releases can also cause cold injury. A strong odor is a warning to act, not a measurement of concentration or a reason to investigate more closely.

Ammonia system materials and components must be compatible with the chemical and the design. Copper, brass and other unsuitable materials can create serious problems. Do not substitute a hose, fitting or seal based only on thread size or availability.

A pressurized or cold release may form a hazardous cloud whose movement depends on release conditions, wind and surroundings. Do not assume that a statement about gas density tells you a safe escape route. Follow the site plan, avoid the cloud and report from a safe place.

Routine operating instruction must identify alarms, controls, prohibited tasks and the safe way to report abnormalities. This knowledge course does not authorize opening a system or entering an affected area. A refrigerant application still needs its own process and emergency instruction.

Basis: 29 CFR 1910.111; NIOSH ammonia guidance; product SDS

10. Provide instructed oversight for ammonia transfer

By the end: Verify continuous attendance, actual instruction and authority before transfer work.

Covered ammonia transfer requires an attendant continuously present in the vicinity during transfer. Do not start or continue on the assumption that someone can check back later. The assigned attendant needs the actual procedure and clear authority to report or stop unsafe work within the approved role.

Tank-car unloading has an explicit requirement: reliable personnel must be properly instructed and have authority to monitor careful compliance with applicable procedures. The job needs both knowledge and authority; a person who is told to ignore a deviation cannot provide effective oversight.

The procedure must address the actual system, communication, access control, required warning arrangements and emergency actions. This course does not provide valve sequences, filling calculations or universal hose-disconnection instructions. Qualified task instruction and equipment-specific verification remain necessary.

If the attendant must leave or a control fails, use the approved safe stopping and handover process. Never abandon an active transfer. Record and resolve deviations through the employer’s system before resuming the affected activity.

Basis: 29 CFR 1910.111(b)(12)(ii), (b)(13)(ii)

11. Select protection and emergency washing facilities

By the end: Verify task-specific PPE and emergency washing, and never treat a stored mask as entry authorization.

The employer must assess exposure and select suitable protection for the actual chemical and task. Splash eye protection, face protection, gloves and clothing must match the hazard. A face shield alone is not a substitute for the required eye protection; ordinary work gloves are not automatically chemical resistant.

Covered stationary ammonia storage installations require at least two suitable gas masks in readily accessible locations and an easily accessible shower or a 50-gallon drum of water. Covered bulk transport vehicles, except farm applicator vehicles, require at least five gallons of water and a full-face mask. These specific provisions do not replace other applicable emergency-flushing duties.

Respirator availability is not permission to enter a leak. Required use needs the respiratory protection program, appropriate selection, medical evaluation, fit testing where required and training. Unknown or immediately dangerous atmospheres require the applicable IDLH protections; a cartridge respirator must not be assumed adequate.

Before work, locate and verify usable emergency washing equipment and the safe route to it. Report missing or obstructed facilities. Do not begin a corrosive-exposure task with a promise that water or protective equipment will be provided later.

Basis: 29 CFR 1910.111(b)(10); 1910.132, 1910.134, 1910.151(c)

12. Withdraw, raise the alarm and obtain aid

By the end: Follow the assigned emergency role, flush exposed eyes promptly and wait for authorized reentry.

Know whether your assigned role is evacuation only or a trained emergency-response role. For a suspected significant release, leave the affected area by the safe route, alert others without entering danger and notify the designated response service. Do not return to close a valve unless that action is within your training, equipment and approved safe procedure.

Call from a safe location. Give the product, location and known conditions without approaching to gather details. Keep people clear, account for the crew and report anyone missing. An unprotected rescue can create another casualty.

For ammonia eye exposure, begin immediate flushing with abundant water for at least 15 minutes and obtain prompt medical assistance. Use the site’s emergency washing and first-aid instructions. Do not use neutralizing chemicals in the eyes or delay flushing to complete paperwork.

Only the authorized response team may determine reentry. Smell, a quiet alarm or an elapsed time does not establish clearance. Course completion is not HAZWOPER responder qualification. An incidental spill and an emergency release require an employer determination based on the hazard and available controls.

Basis: 29 CFR 1910.38, 1910.120(q); OSHA ammonia emergency-response guidance

13. Recognize separate process, transport and fire duties

By the end: Identify related duties and obtain the separate training and implementation required for the actual operation.

An operation may have duties beyond these storage and handling standards. The employer must evaluate process safety management, EPA risk management, transportation, fire-code and state-plan requirements for the actual chemicals, quantities and activities. A small-course title cannot determine applicability.

If OSHA process safety management applies, operators need training on the process, operating procedures, hazards, emergency operations and safe work. Refresher training must occur at least every three years, and more often if necessary, with the required consultation and documentation. This is distinct from a generic chemical-awareness refresher.

Hazmat transportation functions require separate training, testing and records under the applicable DOT rules. Fire-extinguisher education or designated-user training has its own initial and annual requirements under 1910.157(g) when applicable. Emergency response duties require the proper response-level preparation.

Assign owners to evaluate these related obligations and document the outcome. Do not label this course a complete PSM, EPA RMP, transport or firefighter qualification. Additional programs and technical work must be implemented where they apply.

Basis: 29 CFR 1910.119; 1910.157(g); 49 CFR 172 Subpart H; 40 CFR Part 68

14. Verify readiness for the actual workplace

By the end: Document actual understanding and close critical gaps before authorizing work.

Before assignment, identify the employee’s role and the work they may perform. Verify the actual product, SDS, equipment, procedure, storage arrangement and emergency plan. Resolve missing controls before exposing the worker to the task.

Use teach-back and safe observation appropriate to the role. Ask the worker to identify release warnings, required controls, stop conditions and the safe reporting route. For specialized handling, the employer must separately verify practical instruction and competence on the actual equipment.

Record the date, instructor, worker, subjects, observed understanding, corrections and restrictions. These worksheets are practical employer tools, not universal OSHA certification forms. Keep process, transport, respirator and other required evidence under the rules that apply to each record.

A course score shows knowledge performance within this course. It does not approve an installation or authorize a transfer. If the worker cannot explain a critical action, provide further instruction and verify understanding. Review again when the work, chemical or equipment changes or a performance gap appears.

Basis: 29 CFR 1910.110(b)(16); 1910.111(b)(13)(ii); 1910.1200(h)
