protection is contingent on their adherence to the policies and procedures put in place for them.
Appropriate PPE for the Job
As with many other industries, PPE is important to the safety of workers in laboratories as well. Another item on Sang’s list is, “Ensure that the appropriate PPE...is on hand when you need it.” There are quite a few levels of protection that should be considered when it comes to PPE in labs. Here are some of the most common types of gear you might find:
Safety Goggles: As mentioned before, labs are notorious for being home to some of the most hazardous chemicals. These can splash into the into the eyes if an employee is not careful. To mitigate this hazard, employees should look for vision protection suitable for the job, which includes safety goggles that protect not only the eyeball, but the area around the eyes from chemical splash. For a better understanding of what kind of eyewear you should be purchasing, take a look at ANSI’s Z87.1 standard.
Gloves: Your hands can be your best tool, so it is important to protect them. When it comes to the hazards present in labs, it is important to choose hand protection that will keep your hands safe from absorption of chemicals, chemical burns, thermal burns, lacerations and more. Disposable nitrile or neoprene gloves are usually appropriate as protection from incidental splashes or contact with lab chemicals. However, the SDS should be consulted to verify chemical compatibility with the gloves being used.
Protective Clothing: It is important to wear protective clothing that can resist physical and chemical hazards when working in a laboratory, especially when an exposure may occur.
ollowing the rapid innovation, creation and distribution of a vaccine for COVID-19, there is no question that the work done in labs is important. Each day, scientists and researchers are making discoveries that improve our world and save
lives. Keeping these employees safe is of the utmost importance, so understanding the fundamentals of a safe lab are critical.
To better understand how to conduct a safer lab experience for all, I asked Derek Sang Technical Training Manager at Bulwark, for the top practices to ensure protection in these environments. The topics below are just a few of Sang’s top 15 fundamental practices, which we have listed in full in the sidebar below.
Safety is a Daily Duty
On the list of fundamental practices, Sang directs employees of laboratories to, “get involved in your safety program. Make safety part of your day-to-day job and encourage peers to do the same.”
While this is great advice for employees in any industry, this is particularly poignant for hazardous environments where employees are potentially exposed to corrosive chemicals, irritating airborne particles or open fire as well as many other dangers. One of the riskiest behaviors an employee can find themselves exemplifying is complacency. Cutting corners, acting aloof and not following written policies and procedures can lead to dangerous circumstances for everyone involved.
To ensure that all employees feel it is part of their job to take their safety and the safety of others into their own hands. This means including workers in meetings about safety, talking frequently about the changing hazard landscape in their environment and reminding employees that their level of
15 FUNDAMENTAL PRACTICES OF A SAFE LAB
1. Follow the written Environmental Health & Safety affairs (EH&S) policy statement.
2. Read your lab safety manual.
3. Organize a departmental committee of employees and management that meets regularly to discuss EH&S issues.
4. Allocate a portion of the departmental budget to safety.
5. Implement an EH&S orientation for all new employees.
6. Make learning to be healthier, safer and more environmentally friendly an integral part of your education, work and life.
7. Get involved in your safety program, make safety part of your day-to-day job
and encourage your peers to do the same.
8. Be prepared for unannounced laboratory inspections.
9. Identify and correct hazardous condi- tions and unsafe practices.
10. Before conducting an experiment, ask yourself:
■ What are the hazards or potential hazards?
■ What regulatory standards apply to these hazards?
■ What are the prudent practices, protective facilities and personal protective equipment (PPE) necessary to minimize the risk of exposure to hazards?
11. Include health and safety consider- ations in every pre-experiment discussion.
12. Ensure that the appropriate PPE, such as flame-resistant or chemical-splash pro- tective lab coat, is on hand and available when you need it.
13. Develop specific work practices for individual experiments, such as those that involve particularly hazardous materials and/or should only be conducted in a ventilated hood.
14. Don’t allow experiments to run unat- tended unless they are failsafe.
15. Maintain an easily accessible safety library with relevant resources.
