health and safety issues in lab design.  -  spill containment kit
The laboratory itself is a dangerous working environment.
The procedures for implementation and the material requirements for use include specific design standards and considerations set out by the Building Regulations regulatory authority to ensure that personnel have a safe and healthy working environment.
What are the main health and safety issues that should be addressed during the design process?
* Use, storage and containment of hazardous chemicals most clinical laboratories track or identify the use and quantity of chemicals stored in the laboratory as part of their internal health and safety plans.
Regulatory bodies such as the national fire department, the Occupational Safety and Health Administration and the international conference on building regulations stipulate the permitted quantities of chemicals that can be used and stored in laboratories without special protection measures and
Originally used to establish the chemical quantity and type of laboratory fire classification that determines the specific quantity of hazardous chemicals allowed.
The data is then used to determine the size, type and location of storageccabinet (i. e.
, Can be under the counter or independent chemical storage and flammable safety cabinet)
, And/or need to build specialized rooms for the storage and distribution of flammable liquids.
Storage of chemicals and location of flammable safety cabinets (
Especially volatile, corrosive or corrosive chemicals)
The number and location of the security station will be determined (i. e.
, Eye wash, safe shower, fire blanket, leak and cleaning-
And fire extinguishers ).
In the lab.
As a planning tool, laboratory planners have a special form to help them collect data from space.
The data collected includes chemicals used in the laboratory by location, quantity and category.
This enables professional designers to analyze the volume of material for each technical part, determine the storage requirements required to accommodate the volume, and identify its potential location, thereby minimizing the generation of possible potential safety hazards, clear the in and out path for responders and/or personnel.
* Environment: in addition to these physical design problems, the information collected also leads to the identification and consideration of environmental problems, in particular, how and where special ventilation and/or control measures are required to prevent exposure and migration of smoke and odors between technical departments.
Exposure and control are achieved by collecting, isolating and removing harmful smoke and harmful odors, utilizing specialized environmental enclosures and/or tools such as local smoke exhaust, ventilation cabinets, biosafety cabinets, and/or air-
Differential pressure in laboratory space.
Local smoke exhaust devices include lower ventilation, rear ventilation, and ventilation air outlets for histological/general anatomy and Special Chemistry.
Determining the type and location of the fume hood occurs during the evaluation of specific laboratory processes in different technical parts of the laboratory.
For example, chemistry and Special Chemistry tend to use a large amount of volatile and toxic chemicals in the process leading to atomization, evaporation, or mixing emissions that perform best in a closed environment, such as a smoke cover.
Microorganisms and immunology utilize toxic or biohazardous materials in laboratory processes that are best carried out in biosafety cabinets, a similar type of closed environmental equipment. [
Slightly] IllustrationsAir-
The differential pressure is the process of controlling the airflow rate and direction between spaces.
By using negative or positive pressurizing, the direction of airflow from cleaning to dirty areas or from support/assist to lab space can be determined.
One of the biggest problems with maintaining proper ventilation in the laboratory is that the large open space makes it difficult for the entire laboratory to establish effective compression and airflow.
Positioning and introduction of supply/Manufacturing
The air to the Laboratory spacecraft will also affect the effectiveness of the special environmental shell (i. e.
, Fume hood, biosafety cabinet)
Or local air intake, water after eating, water below and snorkeling.
Level 2 of biosafety (BSL2)
Is an ordinary laboratory area, but BSL3 will be a very special environment that needs to be associated with other non-BSL3 space (i. e.
Tuberculosis, fungi or infectious diseases).
* Ergonomics and quality of life air quality is an important health and safety issue, but so is the overall quality of life of laboratory personnel.
Specific Design issues affecting quality of life are lighting, visibility, ergonomics, accessibility, noise and finishes.
Lighting: in order for laboratory personnel to perform work tasks in a safe and healthy environment, laboratory design should provide adequate lighting levels; 75-to 80-

High working face is usually considered to be the lowest level.
The use of indirect/direct lighting units provides a better diffusion distribution, reducing glare and shading.
Introduction of natural light to good health (eye and mental)
, While an external view helps employees reduce stress by providing a sense of time or connection to the outside world.
Visibility: good visibility and clear line of sight between technical departments promote safe work practices and have the opportunity to identify and respond to potential occurrence of security incidents.
This can be achieved by reducing the overhead storage of the lab workbench.
It can also be done by providing a view window between closed workspaces.
Accessibility: provide appropriate cycle gaps in the laboratory to facilitate safe entry and exit between the work area and the workbench;
For example, the latterto-
The rear aisle area should have enough space for someone to pass safely between people working on two benches;
5' 0' clear is a recognized standard.
When adjacent to the fume hood, biosafety cabinet and ultra-deep floor equipment, the depth of the work table should be considered, because highlighting the equipment can create potential cycle hazards.
ADA compliance: consider manual meter height
Washing sink, eyeswash/safety-
The station activator must be considered, as well as the ability to reconfigure/adjust the workstation to accommodate a wheelchair or a technician who is physically damaged.
Ergonomics: the lab case should be a modular, flexible type system that can adjust and reposition working surfaces and storage components.
This adaptability is essential to adapt to changing needs in laboratory processes and staffing.
Due to the limited reach of the staff, it is important to indirectly store the adaptability of the installation height.
The maximum working surface depth should be 30 "to 36 ".
Flexible case work
The system layout should solve the following problems: adjust the working face height to accommodate the staff;
Determine the height of the technician;
For the actual contact of technicians, the depth of the worksheet surface should be considered;
And the ability of overhead shelves behind workstations.
Overhead lab case work components should also address safety issues such as physical lips or edges on open shelves to prevent spills or drops of potentially hazardous laboratory chemicals and/or supplies.
Seat height adjustable, waist support. Slip-
Resistant floors should be used in wet areas and/or areas like histological embedding/cutting stations where paraffin accumulates on the floor and creates a risk of sliding.
Noise: due to the number of automated equipment required to process samples, the noise level in the laboratory is usually high.
The selection of new equipment should include a review of its noise factor, especially for biosafety cabinets, fume hoods, motors and blowers.
The use of acoustic ceilings to help disperse the noise levels in the lab can be improved by lifting them to the highest actual height.

Some agencies use carpets in laboratories to help reduce noise, ergonomics/stress relief, and re-testing due to sample drops, but decisions should be based on operations (cleaning)
Ergonomics and financial considerations because of the trade-offs.
None of these considerations ensure a safe and healthy laboratory environment, unless the culture of the laboratory contains safety in the first place and is highly prioritized.
The laboratory can design these functions as it pleases, but the leaders and users of the laboratory must have security --First mentality
Fortunately, most laboratory managers know that the laboratory itself is a dangerous place and will take corresponding actions when designing and operating the laboratory. Jeffrey R.
