Essential Lab Safety Practices Every Scientist Should Know

Laboratory safety is paramount in any scientific environment, whether it’s an educational institution, research facility, or commercial setting. As a leading provider of bespoke interior design solutions for laboratories, Innova Design Group understands the critical importance of creating spaces that not only facilitate groundbreaking research but also prioritise the safety and well-being of scientists and researchers.

These are the essential lab safety practices that every scientist should know.

Why Is Lab Safety Crucial?

Lab safety is not just about following rules – it’s about creating a culture of safety that protects individuals, valuable research, and the environment. Proper safety practices help prevent accidents, minimise risks, and ensure that scientific work can proceed without interruption. Moreover, adhering to safety protocols is often a legal requirement and essential for maintaining accreditation and funding.

What Are the Fundamental Lab Safety Rules?

Wear Personal Protective Equipment (PPE)

Personal protective equipment is your first line of defence against potential hazards in the laboratory. But what exactly should you wear?
  • Lab coats – Should be worn at all times in the laboratory to protect skin and clothing from chemical splashes and spills.
  • Safety glasses or goggles – Essential for eye protection against chemical splashes, flying particles, or harmful radiation.
  • Gloves – Choose the appropriate type for the chemicals you’re handling. Remember the proper technique for removing gloves to avoid contamination.
  • Closed-toe shoes – No sandals allowed! Protect your feet from spills and falling objects.
  • Face shields – May be necessary for certain procedures with a high risk of splashing or explosion.
Remember, PPE should be worn at all times in the laboratory, even if you’re not directly handling hazardous materials.

Handle Chemicals and Hazardous Materials Properly

Adhering to these lab safety practices helps prevent accidents, minimises exposure to dangerous substances, and ensures a safe and compliant laboratory environment.
  • Always read the Material Safety Data Sheet (MSDS) before working with any chemical.
  • Store chemicals in properly labelled containers and in appropriate storage cabinets.
  • Never use your mouth to pipette chemicals – always use mechanical pipetting devices.
  • Work with volatile or hazardous chemicals in a fume hood to minimise exposure.
  • Be aware of the potential for chemical reactions and never mix incompatible substances.

Use Laboratory Equipment Responsibly

Proper use of laboratory equipment is essential for accurate results and preventing accidents.
  • Receive proper training before using any piece of equipment.
  • Follow the manufacturer’s instructions and safety guidelines.
  • Report any damaged or malfunctioning equipment to your supervisor.
  • Never use equipment for purposes other than its intended use.

Take Precautions When Working with Biological Agents

Prevent contamination and potential health risks by adhering to these safety guidelines for working with biological agents:
  • Work with potentially infectious materials in a biological safety cabinet.
  • Use appropriate disinfectants to clean work surfaces and equipment.
  • Dispose of biological waste in designated containers.
  • Be aware of the potential for contamination and take steps to prevent it.

Dispose of Laboratory Waste Safely

To minimise risks and protect the environment, laboratory waste must always be disposed of according to proper procedures.
  • Segregate waste into appropriate containers (e.g., chemical waste, biological waste, sharps).
  • Never pour chemicals down the sink unless specifically instructed to do so.
  • Use designated containers for broken glass and other sharps.
  • Follow your institution’s guidelines for disposing of hazardous waste.

Ensure General Laboratory Hygiene

To ensure a safe and healthy laboratory workspace, always practise good hygiene.
  • Keep work areas clean and uncluttered to reduce the risk of accidents.
  • Never eat, drink, smoke, or apply cosmetics in the laboratory.
  • Wash your hands frequently, especially before leaving the lab.
  • Tie back long hair and avoid loose clothing that could catch on equipment.

How Should You Respond to an Emergency in the Lab?

Your exact actions will depend on the nature of the emergency. These are general emergency safety practices every scientist should know:
  • Know the location of safety showers, eyewash stations, and first aid kits.
  • Familiarise yourself with emergency procedures and evacuation routes.
  • Report all accidents, no matter how minor, to your supervisor.
  • Keep emergency contact numbers readily available.
Below are safety practices for three specific emergencies: electrical, fire, and radiation.

Electrical Safety: How Can You Prevent Electrical Accidents?

  • Inspect all electrical equipment before use. Never use equipment with frayed cords or exposed wires.
  • Keep electrical equipment away from water and other liquids.
  • Unplug equipment when not in use and never overload electrical outlets.
  • In case of an electrical fire, use a CO2 fire extinguisher, never water.

Fire Safety: What Should You Do to Prevent and Respond to Fires?

  • Know the location of fire extinguishers, fire blankets, and fire alarms.
  • Keep flammable materials away from ignition sources.
  • In case of a small fire, use the appropriate fire extinguisher. For larger fires, evacuate immediately and activate the fire alarm.
  • Conduct regular fire drills and ensure all lab members know the evacuation procedures.

Radiation Safety: How Can You Protect Yourself From Radiation Exposure?

  • Only work with radioactive materials if you have received proper training and authorisation.
  • Use appropriate shielding and minimise exposure time.
  • Monitor radiation levels and use personal dosimeters when required.
  • Dispose of radioactive waste according to strict protocols.

What Role Does Laboratory Design Play in Safety?

At Innova Design Group, we understand that laboratory design plays a crucial role in maintaining safety. Here are some key design considerations:
  • Proper ventilation systems, including fume hoods and local exhaust ventilation.
  • Adequate space for safe movement and operation of equipment.
  • Ergonomic design to reduce the risk of repetitive strain injuries.
  • Appropriate storage solutions for chemicals and hazardous materials.
  • Clear signage and labelling of safety equipment and hazards.
  • Easily accessible emergency equipment, such as safety showers and eyewash stations.

How Can You Create a Culture of Safety in Your Laboratory?

Creating a safety-conscious environment goes beyond following rules. It involves:
  • Regular safety training and refresher courses for all laboratory personnel.
  • Open communication about safety concerns and near-misses.
  • Leading by example – supervisors and senior researchers should always follow safety protocols.
  • Conducting regular safety audits and addressing any identified issues promptly.
  • Encouraging a “stop work” policy if unsafe conditions are observed.
