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 most likely wouldn’t do not forget that the chemical inflicting the widespread most cancers circumstances was hexavalent chromium.
In fact, the risks for people working with and round hazardous chemical compounds have lengthy been identified. And, sadly, for a lot 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 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 compounds, typically 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 incessantly carried out within the aerospace business can pose critical dangers for people from publicity to hexavalent chromium. Vulnerability to respiratory issues brought on by inhalation of hexavalent chromium is critical, largely as a consequence of potential harm to the lungs and airways — and the principle cause for the frequency of publicity is as a result of chromium is often added to the paints used for airplane components.
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 some of these chemical compounds. 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 essential a part of the equation.
Robots can hold people from needing to work straight with these and different hazardous chemical compounds. One of many strongest arguments for robots, on the whole, is their potential to protect people from working within the varieties of uninteresting, soiled and harmful occupations that always 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 typically requires upkeep staff to put on protecting fits and respirators and spend tons of 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. Attributable to labor circumstances in these cramped, tight areas, the U.S. Air Drive has reported a major quantity of shoulder accidents associated to this work. In these circumstances, robots can obtain higher outcomes whereas lowering or eliminating some of these employee accidents.
Up to now, a 2022 research by the Nationwide Library of Drugs discovered that using robots for repetitive web site work can scale back unsafe, monotonous duties by 25-90%, reducing 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 protected distances, retaining people away from harm, or publicity to chemical hazards.

Implementing the precise robotic, the precise manner
To reduce human publicity to hazard whereas additionally gaining the good thing about potential cost-savings, it’s essential to make the most of and set up the precise robotic, and with the proper implementation.
It’s vital to work with a robotic integrator affiliated with the Robotic Trade Affiliation (RIA) who can assist select which sort of robotic is true for the duty. As well as, any robotic set-up ought to have a threat evaluation carried out to make sure that RIA requirements are met.
Among the many methods to satisfy these requirements is through the use of further sensors, emergency cease buttons, and scanners that detect human presence in unsafe areas, and by fencing off robotic work areas. These are only a few of the measures {that a} compliant robotic integrator may arrange and check for security.
Making a protected office tradition
On the finish of “Erin Brockovich,” the decide guidelines towards the power firm that polluted the groundwater, and a hefty settlement is received 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 protected 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 precise security options in place. These embody robotic staff, which by no means get most cancers, respiratory illnesses or shoulder accidents. In the end, they merely can’t get sick or injured.
There’s a mistaken perception amongst some that robotic installations take jobs away from folks. As an alternative, 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 take pleasure in a safer working surroundings whereas concurrently including helpful 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 most certainly assist.
