By François NR Renaud, scientific adviser Gloves, whose origin goes back to antiquity, are elements of hand protection; handling (against abrasion), protection against heat or cold (firefighters, metallurgists, welders), protection against chemical or biological products (chemical industry, laboratories), against CBRN threats, against cuts (butchers). They are therefore personal protective equipment (PPE). As far as…

What’s this about? We have talked several times about the effectiveness of masks in protecting against Covid-19. These include type 1 or 2 surgical masks, FFP1, FFP2 and FFP3, FMP1, FMP2 and FMP3 and alternative category 1 or 2 masks! All the more so since these masks meet different standards whose criteria do not always…

What’s this all about? The pandemic at Covid-19 seems to be going away. For us scientists, it has revealed a very large number of lessons: how to deal with such an emerging virus? what pathogenicity? (small gripette or very serious disease?) ; what treatment (hydroxychloroquine, paparacetamol, remdesivir?); reliability of the viral diagnostic test (30% false…

Some professionals require CBRN protection even though they are already equipped with PPE that specifically protects them in the performance of their job: this is the case for deminers, (EOD Explosive Ordnance Disposal), firefighters exposed to toxic fumes, helicopter pilots or fighter pilots. Ouvry has developed an undergarment that can be worn underneath normal equipment…

Farmers are subject to particular health risks, the main ones being accidental risks (machines…), physical constraints (noise, vibrations…), plant protection products, respiratory problems, biological agents and psychosocial risks (suicide). The handling of chemicals by farmers is undoubtedly an important activity of their profession and we will be particularly interested in personal protective equipment to protect…

Current images show that tear gases are massively used to maintain order during demonstrations. This leads us to ask ourselves some questions to better understand these products: what is their composition, how did they appear, what are their mode of action and toxicity, how can they be protected or even eliminated, what is the legislation…
