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 primarily based on actual occasions, they in all probability wouldn’t keep in mind that the chemical inflicting the widespread most cancers circumstances was hexavalent chromium.

In fact, the risks for people working with and round hazardous chemical substances have lengthy been identified. And, sadly, for a lot too lengthy, unsafe situations within the American office weren’t taken as critically as they need to have been. Lately, that has been altering — and for instance, the Environmental Safety Company (EPA) just lately launched new advisable tips 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 business

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

Fortunately, the aerospace business has begun paying extra consideration to this very critical 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 preserve people from needing to work instantly with these and different hazardous chemical substances. One of many strongest arguments for robots, generally, is their capacity to protect people from working within the sorts of uninteresting, 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 business. 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 lot of hours crawling round on their arms and knees.

It’s almost unimaginable, underneath these situations, to manually apply the coatings at constant speeds and thicknesses. As a consequence of labor situations in these cramped, tight areas, the U.S. Air Drive has reported a major quantity of shoulder accidents associated to this work. In these situations, robots can obtain higher outcomes whereas decreasing or eliminating all these employee accidents.

Thus far, a 2022 examine by the Nationwide Library of Drugs discovered that the usage of robots for repetitive web site work can scale back unsafe, monotonous duties by 25-90%, decreasing human publicity to hazardous conditions by a mean of 72%.

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

Implementing the best robotic, the best approach

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 best robotic, and with the right implementation.

It’s crucial to work with a robotic integrator affiliated with the Robotic Business Affiliation (RIA) who can assist select which form of robotic is correct 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 satisfy these requirements is through the use of additional 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 choose guidelines towards the vitality firm that polluted the groundwater, and a hefty settlement is gained for Erin’s aspect. 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 business that protects people from the results of this chemical, and different occupational risks, is less complicated to implement with the best security options in place. These embody robotic staff, which by no means get most cancers, respiratory illnesses or shoulder accidents. Finally, they merely can’t get sick or injured.

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

They’re robots — they usually’re right here to assist people promote a safer office — an idea that Erin Brockovich would most probably assist.
