How does climate relate to workplace safety?
Climate change can alter previously known exposures and require a review of measures that were once considered sufficient. The ILO identifies relevant areas such as heat, ultraviolet radiation, extreme weather events, air pollution, vector-borne diseases, and agrochemicals. Their importance varies depending on the activity, location, and working conditions.
Not every weather event can be individually attributed to climate change. Prevention doesn’t need to resolve this attribution to address an observed hazard. It should use available information to anticipate plausible scenarios and keep change management up-to-date, preventing design and organizational decisions from depending solely on historical conditions.
Identify exposed people and tasks
The review should identify outdoor activities, hot environments, travel, and work in areas susceptible to flooding, fire, or storms. Exposure may also occur during cleanup, repair, and recovery following an extreme event. These extraordinary tasks often require changes to access, equipment, and coordination compared to normal operations.
It is important to consider contracting companies, temporary staff, shifts, and dispersed locations. The assessment should describe who may be left without communication, shelter, or rapid access to help. Simply stating that a sector is vulnerable is insufficient; sufficiently concrete scenarios are needed to allocate measures, resources, and responsible parties at each center and activity.
Heat, radiation and air quality
Heat stress requires assessment of the environment, physical effort, clothing and recovery, while solar radiation requires specific protection for the skin and eyes. Both hazards can coexist with dust, smoke or other contaminants. A measure that helps control one hazard may affect another and should therefore be reviewed as part of the overall assessment.
For example, keeping entrances closed to reduce smoke entry can alter ventilation and indoor temperature. Choosing respiratory protection can also increase thermal demands. The solution requires an integrated assessment, with criteria for reducing exposure, modifying tasks, or stopping them when adequate protection cannot be guaranteed through available controls.
Extreme phenomena and emergencies
The scenarios should consider supply disruptions, blocked routes, structural damage, and communication difficulties where plausible. The emergency plan needs clear alternatives and activation criteria. Shelters, assembly points, and access routes for external assistance should be verified against the actual site conditions.
Subsequent recovery must also be planned. Activities should not resume simply because the event has ceased if damaged facilities, released substances, or flooded equipment remain. Inspection and authorization for return to service must be carried out by qualified personnel and coordinated among the companies involved in cleanup, repair, and commissioning.
Alerts and operational decisions
Weather alerts and environmental information must translate into predefined decisions. It’s important to establish who reviews alerts, how often, how changes are communicated, and which tasks need modification. The absence of an alert doesn’t eliminate local risks, just as a general alert alone doesn’t describe all positions.
In Spain, Royal Decree 486/1997 outlines measures to address adverse weather conditions in outdoor work and in areas that cannot be enclosed. When an orange or red weather warning is issued and the existing measures are deemed insufficient under the regulations, conditions must be adapted, including reducing or modifying working hours.
Practical example
A maintenance company keeps a schedule designed for previous summers. During a prolonged heat and smoke episode, several outdoor tasks are maintained, and rest and recovery take place in a room whose ventilation is no longer adequate. The controls exist separately, but their combined effectiveness has not been evaluated.
The review redefines priority tasks, recovery zones, and criteria for suspending travel or interventions. It also prepares resources and communication with contractors. This example shows that adapting involves more than just adding a notice to the procedure; it may require changing the work sequence and the infrastructure that allows it to be carried out safely.
Monitoring and improvement
Monitoring should track exposures, the implementation of measures, and incidents, using indicators to inform decision-making. It can record modified tasks, shelter failures, or response times, not just the number of communications sent. Consulting the workforce helps identify difficulties that automated records may not capture.
Investments should consider plausible future conditions and avoid solutions that shift risks to other areas. Maintenance, procurement, and facility design play a preventive role. Periodic reviews should incorporate new information and lessons learned from past events, maintaining traceability of what changed, why, and the outcome.
Common mistakes
Common mistakes include treating climate change as unrelated to operations, acting only in emergencies, or using a generic plan that is the same for all centers. It is also a mistake to assume that adaptation depends solely on individual behavior or on each person staying hydrated and checking the weather.
Managing emerging risks requires transforming scenarios into verifiable actions. Adapting occupational health and safety (OSH) means ensuring that work, equipment, and organization are aligned with current and foreseeable hazards. Preventive responsibility involves assessing risks, preparing resources, making timely decisions, and verifying that measures effectively protect all exposed individuals.
