Thermal Stress Management.
Heat is more than a health risk.
It's an operational risk.
MMS 911 EMS helps mining and high-risk operations identify, quantify and manage thermal risk before it compromises people, compliance or operational performance.

Assess your operation →Explore our approachFrom exposure to operational resilience
Thermal stress sits at the intersection of environment, physiology and operational demand.
Left inadequately controlled, increasing thermal exposure can affect employee health and functional capacity, contribute to fatigue and medical events, increase pressure on emergency-response systems, create regulatory and compliance exposure and ultimately affect the ability of an operation to work safely and effectively.
MMS 911 EMS approaches thermal stress as an integrated health, risk and operational challenge—not simply an environmental measurement or hydration issue.
Compliance
Know where you stand.
Identify regulatory and system gaps, strengthen thermal-risk management programmes and support demonstrable implementation of appropriate controls.
Performance
Protect operational capability.
Understand how thermal exposure interacts with workforce capacity, work practices, emergency risk and operational continuity.
Integrated risk
One risk.
Multiple business consequences.
Thermal risk reaches across environmental exposure, human physiology, occupational health, operational controls, emergency preparedness and regulatory systems.
Managing these elements in isolation can leave important gaps. MMS 911 EMS brings them together into one coordinated view of the operation.
Our integrated approach
More than a heat-stress policy.
Effective thermal-risk management requires different disciplines to work together. MMS 911 EMS integrates occupational health, occupational hygiene, medical surveillance, workforce health, emergency preparedness, risk management and operational controls into a coordinated approach appropriate to the realities of each operation.

From assessment to implementation
What MMS 911 EMS delivers.
Operational Thermal-Risk Assessment
Establish the current thermal-risk environment, exposed work groups, tasks, existing controls, workforce factors and operational vulnerabilities.
Regulatory & System Gap Analysis
Review existing thermal-stress systems against applicable requirements and recognised good practice to identify gaps and priorities.
Executive Risk & Priority Report
Translate technical findings into clear management priorities: what requires attention, why it matters and where intervention should begin.
Operation-Specific Heat Management Strategy
Develop an integrated control strategy appropriate to the mine, workforce, environment and operational realities.
Implementation & Workforce Interventions
Support practical implementation across procedures, controls, workforce education, health interventions and management systems.
Emergency Preparedness Integration
Incorporate severe heat illness into recognition, response, stabilisation, escalation and evacuation systems.
Monitoring, Measurement & Review
Establish meaningful indicators to evaluate whether controls are functioning and where adjustment is required.
Ongoing Specialist Advisory Support
Provide continuing review and specialist input as conditions, operations, workforce characteristics and requirements evolve.
Initial specialist application
Built for complex operating environments.
Mining combines environmental exposure, physical workload, PPE, workforce variability, production requirements and—in many operations—distance from definitive medical care.
Underground, surface and remote mining environments therefore require thermal-risk solutions that work not only on paper, but within the realities of the operation.

Emergency preparedness
When prevention becomes response.
Severe heat illness can become a time-critical medical emergency. In remote and industrial environments, outcomes may depend not only on recognising the condition, but on what happens between first presentation and definitive care.
MMS 911 EMS incorporates emergency preparedness into thermal-risk management—from early recognition and onsite response to clinical escalation, stabilisation and evacuation planning.

Combined capability
Multidisciplinary expertise.
One integrated solution.
Complex occupational risks rarely belong to one discipline. MMS 911 EMS brings together complementary expertise across occupational and clinical medicine, workforce health, emergency medical management, risk and operational environments to develop solutions that consider both the employee and the business.

A practical heat stress management programme for employers.
Managing heat stress in the workplace requires an assessment of the environment, the job and the people doing it. Underground mines, surface operations, processing plants and remote workplaces can have different exposure patterns; their controls and response plans need to reflect those differences.
From risk assessment to a workable control plan.
A review considers heat exposure, physical workload, clothing and PPE, shift patterns, existing controls and workforce factors. These findings inform priorities for engineering measures, work organisation, recovery opportunities, acclimatisation, training, health oversight and emergency readiness. Hydration is one part of this programme.
MMS brings these elements into the thermal-risk assessment, gap analysis, management strategy and implementation support described above. The agreed scope should identify what needs attention, who is responsible and how the operation will monitor progress.
Questions employers ask
What should a workplace heat stress management plan cover?
It should identify exposed jobs and work groups, assess relevant environmental and workload factors, define practical controls, support acclimatisation and training, and establish monitoring and emergency arrangements. The detail depends on the operation and its applicable requirements.
Is providing water enough to manage heat stress at work?
Water access is important, but a heat management programme also considers engineering and work-practice controls, workload, recovery, acclimatisation, PPE and emergency procedures. NIOSH workplace guidance describes this combination of controls.
Why does acclimatisation matter for workers?
Gradual adaptation to work in heat is an important part of managing exposure. New workers and people returning after time away may need particular attention. The approach should reflect the job, conditions and individual circumstances rather than a universal schedule.
How is heat stress management linked to occupational health?
Occupational health helps consider individual susceptibility, medical surveillance and fitness for the work involved. Heat management also needs input from workplace risk, hygiene and operations. Explore our occupational health services.
How do we request a heat stress assessment?
Share your site location, workforce size, work environment, shifts, known heat exposure concerns and existing heat management arrangements. MMS will discuss the assessment scope, available information and priorities for your operation.
