Grow Facilities – Possible Hazards
Lighting
• High intensity lamps• 1000 watt bulbs are common• High electrical demand • Can reach 500 deg F• Emit a great deal of heat.

Grow Facilities – Possible HazardsCO2 Enrichment
Requires Installation Permit
2 major system types:• CO2 gas cylinder • Gas burner (Nat. gas)
Asphyxiation hazards !
Increase growth rate by 25% and crop yields by 40%.
Room CO2 is normally maintained at about 1500 ppm. (Only when grow lights are on)CO2 sensors, safety controls, alarms, and warning signs are required.
Gas burner type also presents a CO hazard. Is a non‐vented fuel‐fired appliance under the International Fuel Gas Code.Requires an oxygen depletion sensor interlocked with an exhaust fan.

Grow Facilities – Possible HazardsFumigationRegulated by fire codes and requires operational permit and hazard signage.
Common types:• Sulfur burners to control mold and mildew.• CO2 fumigation to control pests.
Sulfur burners create sulfur dioxide. Need PPE: Gas mask and goggles.
CO2 fumigation done at 40,000 ppm or higher.Above OSHA's immediately dangerous to life or health level.
Concerns:• Some growers fumigate overnight without permits.• Workers entering the space.• Adjacent tenants unaware of this fumigation activity.• First responders entering in the event of a fire.

Grow Facilities – Possible Hazards
Electrical
Overloaded electrical wiring has caused fires in some grow facilities.
• Increased electric demand due to added grow lights and HVAC units.
• In remodeled buildings, may need to upgrade the electric service.
Governed by the National Electric Code (NEC).
• Extension cords cannot serve as permanent wiring to equipment, lighting, fans, etc.
• Wiring can’t pass through doors, walls,or ceilings.

Grow Facilities – Possible Hazards
Heating, Ventilation, and Air Conditioning
Governed by International Mechanical Code (IMC)
Ventilation
Exhaust systems remove contaminants and odors from the air. Marijuana plants emit a very strong “skunk like” odor.
Common methods of odor control:
• Charcoal filter in exhaust duct
• Ozone generators in exhaust duct
• Ionizers

Grow Facilities – Possible Hazards
Plumbing
Governed by the International Plumbing Code (IPC).
• Water supply lines for irrigation must have back‐flow protection to prevent contamination of domestic water supply.
• Grow rooms should have floor drains.– Remove spilled water and nutrient solutions.
– Drains should be equipped with screensto catch plant material or other debris.

Grow Facilities – Possible HazardsFire Protection
National Fire Protection Association (NFPA)International Fire Code (IFC)International Building Code (IBC)
Grow facilities are classified under IBC as an F‐1 Occupancy, Factory Industrial, Moderate Hazard. If over 12,000 sq. ft., then a fire sprinkler system is required.
Also required:
• Fire walls with one‐hour separation between facility and adjacent occupancy.
• Wall and ceiling finishes with a flame spread index within the specified limits.
• Means of Egress as required in IBC, Chapter 10.– Growers typically do not grow in one large open room. – Need to isolate the plants that are at different stages of growth. – Large converted warehouses can be maze‐like with multiple rooms.

Processing Facilities for Marijuana Infused Products
Oil can be extracted from marijuana plant leaves and buds that is highly concentrated with THC, and is commonly known as “hash oil.”
Extract oil is used in: • Edible goods (brownies, candy, etc…).• Oil can be smoked. • Vapor cigarettes. • Balms and Transdermal patches for pain relief.
Local building and fire code officials will review the extraction process and issue an operational permit.
Most extraction methods use hazardous materials for solvents. The most common solvents used are:
• Butane• CO2• Alcohol

Processing Facilities for Marijuana Infused Products
Butane Hash Oil (BHO) Extraction• Cost effective• Dangerous• Used legally in licensed commercial facilities• Used illegally in homes
Pressurized liquid solvent is passed thru marijuana leaves or buds, removing the THC from the plant. The liquid is then boiled off, leaving the oil behind.
Open releases of butane into the atmosphere are prohibited!
In 2014, there were 32 reported butane hash‐oil explosions in Colorado!

Processing Facilities for Marijuana Infused Products
Legal Butane Extraction • Requires an operational permit.• Must be done with an approved closed system.
Requirements for Approval in Denver, Colorado
• The facility may be classified under IBC as a Group H, High Hazard Occupancy.
• Engineering analysis, signed and sealed by a licensed PE. Based on NFPA 58, Liquefied Petroleum Gas Code.
• Hazardous material exhaust system with hydrocarbon detector.

Residential Facilities Pose Many Concerns
Colorado law allows people 21 and older to grow up to 6 plants.
Lighting and equipment are not always installed by licensed contractors or according to code, and many concerns have arisen.
• Unsafe electrical practices. • Heat from grow lights.• Venting gas‐fired appliances into grow rooms.• Humid grow environment ideal for mold.
Butane hash oil extraction is illegal in residential buildings.
Limit for a single person or house can be greatly increased by:
• Obtaining a doctor’s recommendation for medical marijuana • Multiple adults living in the same house.
Can lead to home invasions.
