Like many security plans, chemical hygiene plans reside paperwork that must be reviewed and up to date usually.
Though plans are sometimes particular to every laboratory, its chemical compounds, and its processes, OSHA specifies sure gadgets that should be contained within the plan. The next ideas will help decrease publicity to chemical compounds in laboratories, full a chemical hygiene plan, and promote employee security.
Use normal SOPs
Every chemical presents a novel set of hazards and should be dealt with accurately to make sure employee security. Nevertheless, for labs that deal with all kinds of chemical compounds, establishing a separate protocol for every chemical complicates coaching and will increase the chance of mishandling and publicity.
A regular working process (SOP) that addresses the usage of appropriate private protecting tools, secure dealing with, secure use, and correct disposal can cowl all chemical compounds in a laboratory. Flip charts, indicators or different supplies can then be used to remind employees of particular chemical hazards.
Air high quality can rapidly be compromised in laboratories, making air flow an essential consider minimizing publicity. To find out if the native exhaust system is sufficient, a superb rule of thumb is that the system ought to be able to at the very least eight to 10 air adjustments per hour when the house is occupied.
Along with the final exhaust system for the laboratory, exhaust hoods are one other instrument to extend security. The Nationwide Analysis Council’s Prudent Practices for Dealing with Hazardous Chemical substances in Laboratories recommends “2.5 linear toes of fume hood house per individual for each 2 employees in the event that they spend most of their time working with chemical compounds . Every fume hood ought to have a steady monitoring system to permit handy affirmation of sufficient fume hood efficiency prior to make use of. »
Retaining flooring clear and dry will assist stop slip-and-fall accidents, the third main explanation for damage and misplaced work time. Storing absorbent mats and wipers in spill-prone areas helps workers clear up spills rapidly, so slip and fall hazards are lowered and publicity is minimized. Offering an acceptable receptacle for used cleansing supplies additionally helps decrease publicity.

Waste disposal procedures must also be established, with waste often faraway from the laboratories to a central storage space. Staff ought to be taught to not pour liquids down drains or to make use of fume hoods to get rid of risky chemical compounds.
A well-organized warehouse promotes security and is extra environment friendly. Placing an individual accountable for the stash will help facilitate correct group and storage within the space. This individual may assist be certain that correct stock ranges are maintained, duplicate orders should not positioned, and expired chemical compounds are disposed of correctly.
Even when cupboard space is restricted, the separation of incompatible chemical compounds in warehouses and the containment of cabinets are two essential components for employee security.
Make a plan for brand new chemical compounds. Earlier than a chemical enters a lab, have a plan for dealing with, storing, and disposing of it correctly.
Utilizing broken glassware will be simply as harmful as utilizing the improper chemical compounds. It would not take a lot for a hairline crack to fail and create a spill. Utilizing containment trays will assist management the mess, however avoiding it within the first place saves money and time and minimizes publicity.
Verification of glassware and tools earlier than every use ought to be a part of the SOP. Staff must also know correctly deal with, label or get rid of any broken merchandise in order that it isn’t reused or returned to service till it’s repaired.
Even seasoned technicians can often spill chemical compounds, so it is essential to know correctly deal with spilled chemical compounds. Spill response plans ought to tackle spill prevention methods, containment procedures, sufficient air flow, when to evacuate, search medical consideration, and reporting necessities. Common drills will assist reinforce the small print of response plans.
Having a spill equipment available in each lab helps skilled employees rapidly comprise and management a spill, serving to to reduce publicity.
Container indicators and labels improve security and function a continuing reminder of particular dealing with, use and disposal procedures.

Having a chemical hygiene plan and ensuring employees perceive the plan and the way it helps them keep away from publicity to hazardous chemical compounds are important OSHA laboratory commonplace necessities.
Coaching is important for all employees earlier than they’re assigned to a laboratory, however the training shouldn’t cease there. An annual presentation will not be sufficient to strengthen safety; coaching ought to be a daily exercise that addresses the numerous totally different points of publicity prevention.
Staff ought to know:
- the placement of the chemical hygiene plan
- location of MSDS and different instructional supplies
- how private protecting tools is chosen, its location, use every half accurately and decide when it must be changed
- the hazards introduced by every chemical and process within the laboratory
- correctly deal with chemical compounds to keep away from publicity
- correctly label containers
- good laboratory hygiene and conduct, comparable to by no means consuming, ingesting, or chewing gum in a laboratory; confine hair and unfastened clothes; and avoiding horseplay and sensible jokes
- use the “buddy system” to keep away from working alone
- assess the process or course of they are going to be performing in order that they solely take the quantity of chemical compounds wanted for the job they’re doing
- handle waste
Though each lab presents its personal set of distinctive challenges, contemplating recognized dangers and planning for dangers forward of time will assist decrease publicity to chemical compounds and guarantee a safer office for everybody.
