== A. Background & Definitions ==

The working environment must be appropriate to ensure adequate and safe working practices and to minimize disturbance that would interfere with the validity of the study.
 

== B. Guidance & Expectations ==
* Experimental rooms must be suitable to meet the requirements of the study.
* Storage rooms for samples, reagents, supplies and equipment should provide adequate protection against deterioration or contamination. Safe storage for hazardous substances should be ensured.
* Animal housing should be performed under controlled conditions (see [[3.4.1.4 Animal environmental conditions]]).
* Handling and disposal of wastes should be carried out in such a way as not to jeopardize the integrity of studies (collection, storage, decontamination, transportation).
* Archiving conditions should protect contents from untimely deterioration.

Extra care has to be taken:
* Where important, environmental parameters such as temperature and humidity should be monitored and acceptance ranges should be defined.
* Where appropriate, there should be contingency plans in case of power failure or other disruption.
* Where special facilities are used they must be regularly checked and maintained (e.g. fume cupboards, heating, ventilation and air conditioning (HVAC), cold rooms).

 
'''PLEASE DO NOT FORGET'''
* Keep maintenance records of special facilities (e.g. fume cupboards, heating, ventilation and air conditioning (HVAC), cold rooms).
* In case of suboptimal working/storage environment conditions (e.g. acceptance ranges for temperature or humidity are exceeded) this should be documented in the study along with impact assessment.
* Any regulations that define additional standards associated with specific laboratory hazards (e.g. ionizing radiation, controlled substances, biohazard, animal allergens) must be adhered to.
