Chemical hazards and ergonomic in laboratories
The use of chemicals in laboratories can lead to toxic risks. Handling substances and chemicals releases specific gaseous, particulate or liquid pollutants. Mixing operations, micron weighing, evaporators and particle grinders generate gases and fine dust, which may sometimes be CMR or explosive.
It is therefore necessary to protect operators during handling and to find solutions to limit their exposure to chemicals, in compliance with the exposure limits and averages defined by regulations and listed by the INRS in tool 65, which you can find at this link. (Tool 65 – INRS)
Many laboratories use fume hoods to confine workspaces and protect laboratory technicians from chemical hazards. The air speeds to be used in these fume hoods comply with standards set out in the INRS practical guides. (INRS ED 795 – Laboratory fume hoods)
Our solutions, from air extraction to insufflation
It is through the breakdown of their workstations that Wattohm protects the health of your operators by ventilating their workstations.
To make your manipulations in the laboratory without risk, Wattohm controls the suction, regulation and compensation of polluted air – In conformity with INRS recommendations, the air extracted in laboratories must be compensated to ensure proper operation.
Thus Wattohm studies, designs and installs solutions adapted to the workstations:
- Suction arm
- Containment chambers
- Inducing devices: Pouyès rings and suction backsplash
- Mobile suction and filtration units
- Filter housings
- Front sensors
- Centrifugal extractors
Laboratories, core business of WATTOHM
Wattohm works with you to define your needs and carry out a customised airflow study. The analysis of your needs and manufacturing processes determines the collection, extraction, filtration and replacement of extracted air with fresh air.
Site constraints, regulations and air purification requirements are taken into account. The protection of the working environment and operators is ensured through the installation of equipment and solutions tailored to the customer’s needs in accordance with the specifications: extraction on workbenches, fume cupboards, weighing stations, during transfers, compensation, flow regulation, filtration of pollutants, etc.
