Different types of laboratories
The work that is being carried out in a laboratory will influence the type of equipment that is used there. Most laboratories will have several large pieces of equipment, numerous smaller pieces and several computers linked in. The storage required will vary with specialist facilities for radioactive, flammable and toxic materials.
Chemistry laboratories
Chemistry laboratories tend to break down into the following generic spaces: organic chemistry, inorganic chemistry, physical chemistry and analytical chemistry.
Biosciences (biology) Laboratories
These laboratories, sometimes also called life sciences laboratories, serve as work spaces for a host of special research interests reflecting the investigators' research direction. They are distinguished by the support space that is required for each laboratory or group of laboratories.
Fume hoods, as well as biosafety cabinets and laminar flow hoods, are used in all areas of bioscience research. Storage for chemicals (solvents and acids) must be provided in accordance with applicable codes.
Physical Sciences Laboratories
Physical science laboratories are distinguished from other types of laboratories in a number of ways.
First, there is only a small amount of built-in furniture.
Second, there is abundance and a variety of electrical power. This, of course, is due to the fact that in most physical sciences research labs the floor space is occupied by an array of apparatus and instrumentation, both home-built and store bought. Almost all of this equipment requires power of varying voltage and amperage... Power and piped services are usually provided from an overhead suspended service carrier.
Medical
A medical laboratory or clinical laboratory is a laboratory where tests are done on clinical specimens in order to get information about the health of a patient as pertaining to the diagnosis, treatment, and prevention of disease.
Crime/forensic Lab
A crime laboratory - often shortened to crime lab - is a scientific laboratory, using primarily forensic science for the purpose of examining evidence from criminal cases.

Storage
These are general guidelines to storage Safely space shelves and racks to accommodate the upright removal of the largest chemical container; prevent tipping and dripping with adequate clearance Identify and substitute safer chemical alternatives Keep hazardous materials away from heat and direct sunlight to prevent the degradation of chemicals and deterioration of storage containers and labels Do not store hazardous materials (except cleaners) under sinks Avoid chemical stockpiling; procure hazardous materials as needed Limit fume hood storage of hazardous materials Conduct periodic cleanouts to minimize accumulation of chemicals Keep all food (including gum), beverages, tobacco and open cosmetics outside the work area

Radioactive

Chemical From reactive metals, including sodium, potassium and magnesium From sodium cyanide, iron sulphide, calcium carbide and other compounds that can react to produce toxic fumes/gases Place combustible organic carboxylic acids (i.e., acetic acid) in a flammable storage locker; store inorganic acids in acid storage cabinets Store acids and bases in air-tight containers with snug-fitting caps; avoid loose lids or glass stoppers; use vented caps when necessary to prevent over-pressurization Keep piranha etch and aqua regia in a fume hood at all times Use non-aluminium drip trays for aqueous sodium and potassium hydroxide solutions; isolate nitric acid when utilizing secondary containment Safely transfer containers of acid and base solutions using bottle carriers Never pour water into acid; slowly add the acid to the water and stir

Flammable and Combustible Liquids Store flammable and combustible liquids away from oxidizers and heat producers Store flammable and combustible liquids in excess of 10 gallons (per room) in approved flammable storage cabinets. Use only approved and well-labelled refrigerators and freezers for storing flammable liquids; never store lunch with science

Safety
General advice: Protect eyes and skin lab safety glasses with side shields lab coats and closed-toe shoes must be worn for basic personal protection
In some laboratories, the conditions are no more dangerous than in any other room. In many labs, though, hazards are present. Laboratory hazards are as varied as the subjects of study in laboratories, and might include poisons; infectious agents; flammable, explosive, or radioactive materials; moving machinery; extreme temperatures; lasers, strong magnetic fields or high voltage. In laboratories where dangerous conditions might exist, safety precautions are important. Rules exist to minimize the individual's risk, and safety equipment is used to protect the lab user from injury or to assist in responding to an emergency.
