Chemical hazards (GHS)A hazard is a potential source of danger or harm. If chemical hazards go unrecognized, unexpected events resulting in personal injury and/or property damage can (and do) occur.Interestingly, the very properties that make a chemical useful are often those that make it risky to use, so you must learn how to safely use (…)
Activities with biological material are separated in 4 class, related to the hazard of the strain manipulated, the scale of the activity, the steps, etc.
Refer to the safety data sheet (SDS) for information about the hazards of a particular gas.The main hazards related to compressed gases are:1. Physical hazard: high pressureThe filling pressure of compressed gas cylinders can be up to 300 bar: there is a danger of burst or rupture due to pressure. As temperature rises the pressure (…)
The SCC strongly suggests to all laser users to follow the online laser safety training. If you have any problems accessing the training, please contact us at [email protected] are classified into 8 classes (1, 1C, 1M, 2, 2M, 3B, 3R, 4). Laser hazardousness increases as the class number increases.Commercial lasers are classified by the manufacturer. (…)
Definition of nanomaterialsIn October 2011, the European Commission adopted the following definition of a ‘Nanomaterial’:A natural, incidental or manufactured material containing particles, in an unbound state or as an aggregate or as an agglomerate and where, for 50 % or more of the particles in the number size distribution, one or more external dimensions is in (…)
Refer to the safety data sheet (SDS) for information about the hazards of a particular cryogenThe main hazards related to cryogenics liquids are:The extreme low temperatures (−196℃ for nitrogen and −269℃ for helium) may induce frostbites upon direct skin contact. Unprotected skin can stick to metals cooled by cryogenic liquids and tear when pulled away.All (…)
If some of the older magnets remains traditional (copper wiring and water cooling) with moderate fields ranging from 0.1 T to 2 T (Tesla, 1 T = 10k Gauss), the new techniques (superconductors) allow to reach static magnetic fields that now exceed 20 T. At the same time there are also large differences in magnetic (…)
Medical supervision for people working with radioactivityAccording to the Radiological Protection Ordinance (RPO), all individuals with professional exposure to ionizing radiation must undergo a medical examination before beginning work with radioactive sources or X-ray generators. Personnel professionally exposed to ionizing radiations must undertake a basic radioprotection safety course and agree to follow the rules established (…)
