Risk Assessments in Laboratories: How to Conduct & Document Them

Laboratories are environments where precision and safety must coexist. Whether conducting chemical analysis, mechanical testing, thermal characterization, or environmental simulation, the hazards present in a testing laboratory — chemical exposure, equipment failures, high temperatures, pressure, electrical risks, and biological agents — demand systematic, documented, and regularly reviewed risk assessments.

Risk assessment in laboratories is not merely a regulatory requirement; it is the foundation of a safety culture that protects personnel, preserves sample integrity, and ensures the reliability of test results. This blog outlines the key elements of effective laboratory risk assessments and how they apply to material testing environments.

What Is a Laboratory Risk Assessment?

A laboratory risk assessment is a structured process for identifying hazards associated with laboratory activities, evaluating the likelihood and severity of potential harm, and implementing controls to eliminate or reduce risk to acceptable levels. It is a proactive, evidence-based tool that should be documented and updated regularly.

The risk assessment process typically follows a five-step framework:

1. Identify hazards — physical, chemical, biological, ergonomic, and electrical
2. Determine who might be harmed — laboratory personnel, visitors, contractors
3. Evaluate risks — probability and severity of harm
4. Implement controls — eliminate, substitute, engineer, administrate, or use PPE
5. Review and update — after incidents, process changes, or at scheduled intervals

Types of Hazards in Material Testing Laboratories

Chemical Hazards

Material testing frequently involves corrosive reagents, organic solvents, heavy metal solutions, and hazardous gases. COSHH (Control of Substances Hazardous to Health) assessments and Safety Data Sheet (SDS) reviews are essential components of chemical risk management.

Mechanical and Physical Hazards

Tensile testers, impact rigs, hardness testers, and rotating machinery present entrapment, crush, and projectile risks. Risk assessments must cover machine guarding, safe operating procedures, and load limit protocols.

Thermal Hazards

Furnaces, ovens, autoclaves, and cryogenic equipment are common in testing labs. Burns, fires, and pressure-related incidents are real risks that require documented control measures including thermal PPE and equipment inspection schedules.

Electrical Hazards

Electrochemical testing equipment, high-voltage power supplies, and electronic test instruments present electrocution and arc-flash risks. Electrical risk assessments must address insulation integrity, grounding, and lockout/tagout (LOTO) procedures.

Ergonomic and Environmental Hazards

Manual handling of heavy samples, repetitive pipetting, and exposure to noise or vibration require ergonomic assessments to prevent musculoskeletal injury and occupational illness.

Regulatory Frameworks Governing Laboratory Risk Assessments

Laboratories operating in regulated environments must comply with applicable health and safety regulations. In the United States, OSHA standards — particularly 29 CFR 1910.1450 (Occupational Exposure to Hazardous Chemicals in Laboratories) — set the framework for laboratory safety programs. ISO/IEC 17025 accreditation requirements also include provisions for laboratory safety management as part of quality system documentation.

Risk Assessment in the Context of Material Testing

Material testing laboratories conduct a wide variety of test methods under ASTM, ISO, and proprietary standards. Each new test method introduced into a laboratory workflow should trigger a specific risk assessment:

• Hardness testing (Rockwell, Brinell, Vickers): Risk of projectile indenter fragments, equipment pinch points
• Tensile and impact testing: Risk of sudden specimen fracture and energy release
• Thermal analysis (TGA, DSC): Risk from high-temperature furnaces and volatile decomposition products
• Electrochemical testing: Risk from electrolyte solutions and electrical equipment
• Environmental chambers (humidity, salt spray, UV): Risk from chemical exposure and pressurized systems

Implementing an Effective Laboratory Risk Assessment Program

Effective risk management in laboratories involves more than a paper exercise. It requires:

• Trained personnel who understand the hazards of their specific test methods
• Documented procedures that integrate safety controls into standard operating procedures (SOPs)
• Regular audits to verify that controls are being followed and remain effective
• Incident reporting systems that capture near-misses and enable corrective action
• Management commitment to provide resources and maintain a safety culture
