California employers fined $1.75 million for confined space worker death
A worker who descended into a well to perform cleaning in advance of a welding crew was found dead, suspended from a fall protection harness. Investigators determined that a welding torch left in the well was leaking argon, an odorless gas that displaced oxygen in the confined space.
The employer and three contractors face combined penalties of more than $1.75 million. Among the violations were failure to: evaluate the workplace to determine if any spaces are permit-required confined spaces, ensure employees use equipment and safety precautions during the rescue of an employee, and monitor unauthorized entrants into workspaces.
Confined space hazards exist in many workplaces. Employer’s duties include identifying and labeling confined spaces, establishing and maintaining onsite emergency response plans, and providing training for workers and supervisors. Common types of confined spaces are tanks, silos, pipelines, sewers, storage bins, ovens, drain tunnels, and vaults.
A permit-required confined space is one that, among other things, has the potential to contain a hazardous atmosphere. Even if the space does not normally have that potential, operations such as welding in the space may introduce or create such a hazard. Without proper safety measures, gases and or vapors in a confined space may overcome a worker, or a lack of oxygen may suffocate them.
Employers that identify permit-required confined spaces and create a process for entry must consider four roles:
- Authorized Entrants who actually enter the space;
- Attendants stationed outside the space to monitor the authorized entrants and perform duties assigned in the permit space program;
- Entry Supervisors responsible for determining if acceptable entry conditions are present, for authorizing entry and overseeing entry operations, and for terminating entry as required; and
- Rescue Service personnel who are designated to rescue employees from permit spaces.
According to federal OSHA, there were 1,030 worker deaths in confined space incidents from 2011 to 2018.
Key to remember: Confined spaces may become permit-required depending on the type of work being done in the space.
