Space heaters are not inherently an OSHA violation, but they are heavily regulated. OSHA has no specific standard for space heaters, but they rely on the General Duty Clause, which requires employers to eliminate recognized workplace hazards.
OSHA mandates that all electrical equipment, including space heaters, must be approved by a Nationally Recognized Testing Laboratory (NRTL) and used according to the manufacturer's specifications.
OSHA's Top 10 Most Frequently Cited Standards
However, if space heaters are used improperly, are not kept clear from combustible materials or are not functioning properly, they can cause fire or electric shock or produce carbon monoxide (CO) gas.
Most indoor heaters tend to dry out the air, lowering indoor humidity levels. Dry air can cause irritation to the respiratory tract, leading to symptoms like dry throat, cough, and nasal congestion. For individuals with chronic respiratory diseases like asthma or COPD, low humidity can exacerbate symptoms.
The most common causes of death in COPD patients are cardiovascular diseases (such as ischemic heart disease and heart failure), respiratory failure (often triggered by acute exacerbations), and lung cancer.
It takes time for your home to warm up and cool down. If you're not sure how long it takes, try turning the heating on about 30 minutes before you need it. You should turn it off 30 minutes before you'll stop needing it.
Space heaters are generally not bad for your health, but they pose significant fire and air-quality hazards if used improperly. The most immediate risks stem from skin and respiratory irritation, accidental burns, and the production of toxic fumes.
OSHA’s heat stress requirements mandate that employers take specific, actionable steps to protect workers from heat-related illness and death. While federal heat rules are highly enforced through the OSHA Heat Exposure Emphasis Program, certain states like California (Cal/OSHA) and Oregon have their own specific standards.
Do not use an extension cord or power strip, which could overheat and result in a fire. Do not plug any other electrical devices into the same outlet as the heater. Place space heaters on level, flat surfaces. Never place heaters on cabinets, tables, furniture, or carpet, which can overheat and start a fire.
For the 15th consecutive year, the number one OSHA violation is Fall Protection – General Requirements (29 CFR 1926.501). Specifically targeting construction, this standard covers the failure to provide adequate guardrails, safety nets, or fall arrest systems for workers operating on surfaces with unprotected edges 6 feet or higher.
The 5 largest OSHA fines in history
Look for overhead power lines before handling or climbing a ladder. Maintain a 3-point contact (two hands and a foot, or two feet and a hand) when climbing/ descending a ladder.
Always plug electric space heaters directly into a wall outlet and never into an extension cord or power strip, to prevent overloading and causing a fire. Never leave portable heaters turned on while sleeping. Fuel-burning portable heaters should never be refueled while in use.
There are various informal guides to safe working temperatures, and generally, the acceptable zone of thermal comfort for most types of work lies between 16 degrees C - 24 degrees C (about 61 - 72 F).
Heaters should be plugged directly into a wall outlet and never into extension cords or power strips, which can overheat and ignite. Space heaters should never be left unattended and should always be turned off when leaving the room or going to sleep.
The safest space heaters are oil-filled radiators and modern ceramic heaters with built-in safety features like tip-over sensors, automatic overheat shutoff, and cool-touch exteriors. Always choose models that are ETL or UL certified and keep them at least three feet away from flammable items.
Keep away from water: Never place a space heater near water sources or use it in humid conditions. Water can damage the heater and the electrical components, increasing the risk of fire or electrocution. Check for damage: Regularly inspect the heater for any damage, such as frayed wires or cracked plugs.
Space heaters provide extra warmth to a drafty room or chilly home office, but they can easily pose a safety risk if you don't use them properly. Portable space heaters were involved in an average of 1,600 house fires a year from 2019 to 2021, according to the Consumer Product Safety Commission (CPSC).
The 20-20-20 rule is an ergonomic guideline to prevent digital eye strain. It recommends that for every 20 minutes spent looking at a screen, you should take 20 seconds to look at an object at least 20 feet away.
Answer: OSHA does not require employers to provide heat or air conditioning for work spaces. OSHA does recommend temperature control in the range of 68-76°F.
For humans, "too hot to work" is determined by a measurement called the wet-bulb temperature. This critical limit occurs when the air is so hot and humid that the human body can no longer cool itself through sweating.
Key points about carbon monoxide poisoning
A common source is unvented space heaters. Symptoms of CO poisoning include headache, dizziness, weakness, nausea and vomiting, rapid heartbeat, shortness of breath, seizures, chest pain, disorientation, and loss of consciousness.
Yes, space heaters can make you sick, largely due to how they affect indoor air quality. The specific risks and symptoms depend on the type of heater you are using.
Broadly, heat pumps are the most efficient form of heating. They can be more expensive than a furnace, especially if you purchase a geothermal heat pump. However, geothermal heat pumps are one of the cleanest heating options on the market. A geothermal heat pump can produce 1/6th the CO2 of a natural gas furnace.
