Houston’s ice storm has come and (hopefully) gone. In its wake, however, have been left crashes and other cold-related injuries. Earlier this week, we touched on the dangers of snow/ice storms for traffic and commuters; today, we’d like to focus on industrial workplaces.
Cold weather creates a unique set of hazards for industrial workplaces, particularly refineries, oil and gas facilities, chemical plants, and other heavy industrial sites. Unlike regions that regularly experience freezing temperatures, many industrial operations in Texas and the Gulf Coast are designed for heat, humidity, and year-round production. When temperatures drop suddenly, equipment, infrastructure, and workers are exposed to risks that are not always adequately mitigated.
Equipment Failures and Process Disruptions
One of the most significant cold-weather risks in refineries and industrial facilities involves equipment failure and potentially chain-reaction explosions. Freezing temperatures can cause liquids inside pipes, valves, and process lines to thicken or freeze, leading to blockages and pressure buildup. When frozen lines are not properly identified and managed, they can rupture, releasing flammable, corrosive, or toxic substances.
Metal components also behave differently in cold conditions. Steel becomes more brittle as temperatures drop, increasing the likelihood of cracking or fracture under stress. Gaskets and seals may shrink, creating leaks at joints and flanges. Instrumentation such as pressure gauges, sensors, and control valves may give inaccurate readings or fail entirely, increasing the risk of human error during operations.
In refineries and chemical plants, these failures do not occur in isolation. A single frozen valve or ruptured pipe can trigger shutdowns, emergency releases, or cascading system failures across multiple units.
Increased Risk of Fires and Explosions
Cold weather can elevate fire and explosion risks in industrial settings in several ways. As equipment contracts in low temperatures, small leaks of flammable gases or liquids may develop. These leaks are often harder to detect in cold, windy conditions when workers can’t wait to get out of the cold, allowing vapors to accumulate before being noticed.
Temporary heating measures also introduce hazards. Portable heaters, heat tracing systems, and improvised warming solutions are commonly used to prevent freezing. When installed improperly or maintained poorly, these systems can ignite nearby combustible materials or overload electrical circuits.
Additionally, emergency shutdown systems may not perform as expected in freezing conditions. Valves that fail to close fully or sensors that misread temperatures can delay critical responses during an incident.
Slips, Falls, and Worker Injuries
Cold weather significantly increases the risk of physical injuries to workers. Ice formation on walkways, scaffolding, ladders, and metal grating creates dangerous slip-and-fall hazards. These risks are amplified in refineries and industrial plants, where workers are often forced to work on elevated platforms, narrow catwalks, and in congested work areas.
Bulky cold-weather gear can further complicate movement. Heavy gloves may reduce dexterity, increasing the chance of dropped tools or improper handling of equipment. Insulated clothing can restrict visibility or range of motion, making it harder to maintain balance or respond quickly to hazards.
Cold stress itself is another concern. Prolonged exposure to low temperatures can lead to numbness, reduced reaction time, and impaired judgment. In severe cases, workers may experience hypothermia or frostbite, particularly when wind exposure is high or clothing becomes wet.
Staffing Challenges and Fatigue
Cold weather events often coincide with staffing shortages. Travel disruptions, school closures, and hazardous driving conditions can prevent workers from reporting to their shifts. Facilities may respond by extending shifts or operating with reduced crews, increasing fatigue and stress among remaining personnel.
Fatigue is a well-documented contributor to industrial accidents. Tired workers are more likely to overlook warning signs, bypass safety procedures, or make critical mistakes. In complex environments like refineries, even minor errors can have serious consequences.
Maintenance and Emergency Response Limitations
Cold weather can delay routine maintenance and emergency repairs. Outdoor work becomes more difficult and time-consuming, while frozen ground and equipment restrict access to critical areas. Emergency responders may also face slower response times due to road conditions or limited visibility.
If an incident occurs during freezing conditions, containment and cleanup efforts may be compromised. Water-based fire suppression systems can freeze, foam systems may not deploy correctly, and containment booms or barriers may fail in icy conditions.
Preventive Measures and Safety Planning
Industrial facilities that operate safely during cold weather typically implement detailed winterization plans. These may include insulating pipes and valves, installing and maintaining heat tracing systems, conducting cold-weather equipment inspections, and providing specialized training for workers.
Equally important are administrative controls, such as adjusting work schedules, enforcing rest breaks, monitoring weather forecasts, and conducting hazard assessments before temperature drops. Clear communication and strict adherence to safety protocols are critical during these periods.
When Cold Weather Leads to Injuries
Despite preventive efforts, cold-weather incidents still occur, particularly during sudden freezes or unusually severe weather events. Workers may be injured by falls, equipment malfunctions, chemical exposures, fires, or explosions linked to cold-related failures. Cold weather may be temporary, but its effects on industrial workplaces can be lasting. Attorney Hilda Sibrian has served the Houston workforce for over 20 years.
