 For samples or deliveries manipulation in dry ice or with the cryopod, instead of the classical cryogloves described above, white gloves to be worn under the regular nitrile glove can substituate the cryogloves. It will enable an improved dexterity.

+Cut-protective chemical-resistant gloves.
+
+**Recommended For:**
+
+•	Removal of broken glassware
+
+•	SPILL or leakage cleanup
+
+#### Gloves for classical lab activities
+
+Wear gloves when handling biological materials or chemicals. 
+Hands must be washed thoroughly after removing gloves.
+During the classical lab work, you may want to protect yourself or your samples by wearing disposable gloves. 
+The gloves recommended are nitrile gloves as they trigger less allergy reaction than latex ones. 
+They provide a certain level of protection to work with chemicals but are not replacing the chemical gloves required for the work with strong chemicals. 
+Always consult the safety data sheet to make sure you wear the appropriate glove. In case of doubt contact your safety officer.
+
+There are different types of nitrile gloves because the difference between the various classes is the resistance to penetration of hazardous substances. 
+Precautionary statement for the gloves is proposed, if necessary, in the section 2 (hazard identification) of the safety datasheet. 
+Section 8 of the safety datasheet (exposure control/personal protection) provide detailed information about the personal protective equipment required for the product in use.

+- General lab activities.
+
+Note: Disposable gloves must be discarded after each use or when they become contaminated.

+
+These purple nitrile gloves are ticker and longer than the classical blue gloves. They are 4x more expensive than the classical blue gloves, therefore their usage should be linked to the activities. 
+
+**Recommended For**
+
+- General lab activities where extra protection is required ex: work with DNA labelling reagents.
+
+Note: Disposable gloves must be discarded after each use or when they become contaminated.
+
+##### How to wear and remove disposable gloves?
+It is not that trivial to safely wear and remove disposable gloves without becoming contaminated, please watch the video in [DOCEBO platform](https://unisupport.docebosaas.com/learn/course/52/play/332:103/how-to-wear-and-remove-gloves;lp=3 ).
+
+### Respiratory protection
+
+Collective protective equipment is the always the preferred option to be protected against airborne biological hazards or chemicals. Therefore, biological hazards should be manipulated under biosafety cabinets and chemicals under chemical hoods. However, risk assessment made in collaboration with the safety officer may lead to the recommendation to wear respiratory protection such as FFP2 / N95 respirators or surgical masks under particular circumstances. 
+
+If this is the case, observe the general recommendations for the usage of the respirators:
+
+•	respirators must be properly fitted and tested before use
+•	respirators have a maximum wearing duration, observe the manufacturer ‘s recommendations
+•	Discard the respirators in the adequate waste bins
+

+
+#### Surgical masks
+
+The main intended use of surgical masks is to protect patients and the clinical area from infectious agents from the nose and mouth of the person wearing the mask. As such, they are not classified as respiratory protective equipment. However, in certain situations and if worn properly, a surgical mask and additional eye protection can protect the wearer against droplets and splashes of potentially contaminated liquids. 
+It is important to note that not all surgical masks offer splash protection.
+
+#### Particle filters (FFPX)
+
+Particle filters trap and hold particles (dust, mist, fumes, smoke, microorganisms) from the air flowing through them. Large particles are easier to trap than small ones. These filters can be used against both solid particles and liquid particles (mists, fine sprays and aerosols). 
+
+Particle filters are classified according to their efficiency. Different classification systems exist (based on various national and international standards).
+
+<div align="center">

+</div>
+
+Ref: WHO Manual 4th edition 2020.
+
+As a filter is used, it becomes loaded with the contaminant(s) and eventually becomes blocked. 
+This makes it difficult for the air to flow through the filter and indicates that it should be replaced. 
+Sometimes, the blockage might impair the efficiency of the filtration media by decreasing its global electric charge or even reversing it. 
+As a result, pores might form in the media that could allow the passage of hazardous particles. 
+Follow the manufacture‘s recommendation for the maximum usage duration.
+
+The masks we use are as follows:

+
+ 
+Usage: The face mask in the spill kit. Ensure protection against particles and limited protection against chemical vapors due to the charcoal coating. A valve helps the breathing.
