In “Erin Brockovich,” the Hollywood field workplace hit from 2000 starring Julia Roberts, the title character heroically fights to assist win a lawsuit for residents of a California metropolis affected by groundwater contamination. Whereas many theatergoers noticed the film, which was based mostly on actual occasions, they in all probability wouldn’t keep in mind that the chemical inflicting the widespread most cancers circumstances was hexavalent chromium.

After all, the risks for people working with and round hazardous chemical substances have lengthy been identified. And, sadly, for much too lengthy, unsafe circumstances within the American office weren’t taken as severely as they need to have been. Lately, that has been altering — and as an example, the Environmental Safety Company (EPA) lately launched new really useful pointers for human publicity to hexavalent chromium. As highlighted in “Erin Brockovich,” hexavalent chromium, or Cr(VI), is a big group of chemical substances, usually produced in industrial workspaces, that has been identified to trigger a wide range of illnesses in people, together with lung most cancers.

Hexavalent chromium risks in aerospace trade

As documented by the Occupational Security and Well being Administration (OSHA), portray and sanding duties continuously carried out within the aerospace trade can pose severe dangers for people from publicity to hexavalent chromium. Vulnerability to respiratory issues attributable to inhalation of hexavalent chromium is important, largely as a result of potential injury to the lungs and airways — and the primary cause for the frequency of publicity is as a result of chromium is usually added to the paints used for airplane elements.

Fortunately, the aerospace trade has begun paying extra consideration to this very severe matter, making a heightened consciousness of the hazards of working intently with all these chemical substances. However, along with rising consciousness and regulatory protections, there are additional methods to maintain people safely away from these and different hazardous substances — and robots are an necessary a part of the equation.

Robots can hold people from needing to work straight with these and different hazardous chemical substances. One of many strongest arguments for robots, typically, is their potential to protect people from working within the sorts of boring, soiled and harmful occupations that usually compromise employee security.

Avoiding different office accidents

Along with hexavalent chromium publicity, there are additional dangers for staff within the aerospace portray trade. As an illustration, when jet-engine inlets are manually recoated, the work usually requires upkeep staff to put on protecting fits and respirators and spend a whole bunch of hours crawling round on their arms and knees.

It’s practically inconceivable, beneath these circumstances, to manually apply the coatings at constant speeds and thicknesses. Resulting from labor circumstances in these cramped, tight areas, the U.S. Air Pressure has reported a major quantity of shoulder accidents associated to this work. In these circumstances, robots can obtain higher outcomes whereas lowering or eliminating all these employee accidents.

Up to now, a 2022 examine by the Nationwide Library of Medication discovered that using robots for repetitive website work can cut back unsafe, monotonous duties by 25-90%, reducing human publicity to hazardous conditions by a median of 72%.

How do they do it? One efficient technique is teleoperation, which permits for distant management of robots from secure distances, protecting people away from damage, or publicity to chemical hazards.

Implementing the proper robotic, the proper manner

To reduce human publicity to hazard whereas additionally gaining the good thing about potential cost-savings, it’s necessary to make the most of and set up the proper robotic, and with the right implementation.

It’s crucial to work with a robotic integrator affiliated with the Robotic Trade Affiliation (RIA) who may also help select which sort of robotic is true for the duty. As well as, any robotic set-up ought to have a danger evaluation carried out to make sure that RIA requirements are met.

Among the many methods to fulfill these requirements is by utilizing further sensors, emergency cease buttons, and scanners that detect human presence in unsafe areas, and by fencing off robotic work areas. These are just some of the measures {that a} compliant robotic integrator would possibly arrange and take a look at for security.

Making a secure office tradition

On the finish of “Erin Brockovich,” the decide guidelines in opposition to the vitality firm that polluted the groundwater, and a hefty settlement is received for Erin’s facet. The film implies that the corporate had a tradition of not caring about human well being, which led to their detached dealing with of hexavalent chromium and a subsequent rise in most cancers circumstances.

Making a secure office within the aerospace trade that protects people from the consequences of this chemical, and different occupational risks, is simpler to implement with the proper security options in place. These embody robotic staff, which by no means get most cancers, respiratory illnesses or shoulder accidents. Finally, they merely can not get sick or injured.

There’s a mistaken perception amongst some that robotic installations take jobs away from individuals. As an alternative, within the aerospace trade, these are sometimes the identical personnel who’re then retrained to load, run, clear up and keep the brand new robots. Consequently, human staff take pleasure in a safer working atmosphere whereas concurrently including beneficial technical expertise to their resumes.

They’re robots — and so they’re right here to assist people promote a safer office — an idea that Erin Brockovich would more than likely assist.
