Create a site-specific plan that tells every worker how to raise an alarm, who takes charge, what to do for each threat, and how to confirm people are safe. Start with the greenhouse’s hazards and layout; then assign decision-making and communication roles, write scenario instructions, and train staff to use them. In the United States, OSHA’s emergency action plan (EAP) guidance is a useful workplace baseline, but which requirements apply depends on the operation and applicable standards. Check local rules and coordinate with relevant emergency authorities.
1. Assess the site and its hazards
Walk the property with workers who understand its daily operations. OSHA recommends accounting for hazards inside and outside the workplace, as well as the site’s layout, structural features, and emergency systems. Use the assessment to decide which events need a response procedure and what staff can safely do.
Record the greenhouse address and responder access instructions, operating hours, shifts, exits, assembly and safe-refuge locations, alarms, backup communications, utility shutoffs, chemical storage, relevant safety information, first-aid supplies, spill equipment, and the person responsible for a current headcount. Put these details on a site map that staff and responders can interpret quickly.
Consider whether fire, power loss, heating or cooling failure, water interruption, storm damage, flooding, chemical release, disease-related restrictions, loss of site access, communications failure, or an absent critical operator could threaten people or operations. These are prompts for a site-specific assessment, not a definitive list of regulated hazards.

2. Build a usable contact register
List contacts in a controlled, easy-to-find format. OSHA says covered EAPs include contact names, titles, departments, and telephone numbers; its guidance also recommends posting emergency numbers and making facility contacts accessible.
- Internal: emergency coordinator and deputy, owner or manager, shift leads, and anyone assigned to account for workers or perform an authorized shutdown.
- External: local fire/rescue and emergency medical services, utility providers, building or landlord contacts, relevant public agencies, and poison or chemical emergency contacts where applicable.
- For each entry: name, role, primary and backup number, preferred contact method, hours when the contact is available, and last-verified date.
Keep the current list at a known staff location and maintain an accessible backup outside the primary site in case it is inaccessible. Name the person who updates it and explain how workers will be told about changes. Identify an alternate communications facility or method if the greenhouse or its primary communication system is unavailable.

3. Define who is in charge and who does what
Write the escalation chain as short actions, not a vague instruction to “notify management.” OSHA advises employers to identify an emergency coordinator and stresses that workers should know who that person is and understand their authority to make decisions during emergencies.
- Discoverer: Raise the alarm using the site’s stated method. Report the location, hazard, people affected, and any immediate danger without entering a hazardous area.
- Shift lead: Start the relevant scenario procedure, direct nearby workers as trained, and call emergency services when the procedure or circumstances require it.
- Coordinator: Decide whether the plan is activated, direct internal response, ensure outside services are notified when needed, meet responders, keep access clear, and direct any required shutdown.
- Deputy: Assume the coordinator’s duties if the coordinator is absent or unavailable.
- Accountability lead: Take the roster or other headcount method to the designated location and report missing or unaccounted-for people to the coordinator or incident commander.
- Authorized shutdown staff: Perform only the specific shutdown tasks for which they are named, trained, and authorized, and only when it is safe to do so.
For emergency response operations covered by OSHA’s HAZWOPER standard, the emergency response plan must include personnel roles, lines of authority, and communication; the senior responding emergency official takes charge of a site-specific Incident Command System. That rule applies to covered operations, not automatically to every greenhouse.

- Compact Walk-in Greenhouse: The greenhouse features a sloped roof to avoid water buildup. Measuring 76.8 x 30.3 x 66.1 in, it provides ample space for vegetables, flowers, and potted plants, allowing easy watering. Note: Install it in a sheltered location
- Reinforced Steel Frame: This portable walk-in greenhouse is made of thick powder-coated steel with top support bar for overall stability. Ground stakes and guy ropes help secure it firmly on lawns. It performs reliably in windy and rainy conditions
- Optimal Growing Environment: Our walk-in plant greenhouse uses a 140 gsm PE cover that allows sufficient sunlight while providing insulation, Level 6 sun protection, and water resistance. The durable PE material resists tearing for long-term outdoor use
- Easy Access & Ventilation: This walk in green house includes a zippered roll-up door and 2 windows with tie straps. They allow convenient roll-up access while promoting airflow and keeping animals out. It also extends the growing season for better results
- Easy Assembly: The walk in greenhouse includes clear instructions and a quick-connect frame for simple setup without complicated tools. U-shaped ground stakes help secure the base firmly. The extended bottom edge allows added weight for extra stability
4. Write a separate response card for each credible hazard
A contact list cannot tell staff whether to evacuate, shelter, or stay at a refuge point. Create a short, accessible card for every scenario identified in the site assessment. Each card should state:
- How to recognize and report the event, and which alarm or backup method to use.
- Who is notified, in what order, and who decides whether to activate the plan.
- Whether workers should evacuate or shelter, the route or location to use, and who authorizes re-entry or an all-clear.
- How to account for staff, visitors, and contractors, and who reports anyone missing.
- Any shutdown task that is safe, who is authorized to do it, and when staff should leave it to responders.
- How to direct responders to the scene, including gates, access routes, hazards, and relevant site information.
Do not assume one assembly point suits every event. OSHA notes that the appropriate assembly or refuge location can differ by threat—for example, a tornado may require a different response from a chemical spill or fire. Select routes and locations against the site map and, where appropriate, local responder advice.

Example: fire
Specify the alarm method, evacuation routes, a fire-appropriate assembly location, the person who calls emergency services, the headcount process, and who meets responders. Do not assign staff to fight a fire or shut down equipment unless that duty is specifically authorized, trained, and safe under the procedure.
Example: chemical release
State how to report the substance and location without approaching it, who decides whether to evacuate or use another safe refuge, and how to keep workers and responders away from the affected area. Point to the relevant chemical information and spill equipment, but do not direct untrained staff into a release area.

Train every worker to recognize relevant hazards, raise an alarm, give a clear report, follow evacuation or shelter instructions, reach the correct location, and understand their assigned role and its limits. Train coordinators and designated shutdown staff for their specific duties. OSHA’s training topics include roles, threats, notification, alarms, evacuation, shelter, accountability, equipment, and authorized shutdown.
Practice scenarios as appropriate for the site. After an exercise, have workers and management review what worked, identify gaps, and improve the instructions. OSHA advises drills as needed and evaluation after drills; emergency response plans covered by HAZWOPER must be rehearsed regularly and be compatible with relevant public-agency response plans.

A posted emergency contact board or document holder can make the current information easier to find, but it does not replace a complete plan, training, or drills.
