Ensuring Safety: Modifying PLC Programs on Unsafe Machines and Ethical Dilemmas

Question:

In a hypothetical situation, an employer possesses a machine that does not meet safety standards: hydrogen gas torch systems lacking safety shutoff valves, an industrial robot controlled by non-safety PLC outputs, and various safety hazards in the control cabinet. The employer requests modifications to the PLC program for operational reasons. Past advice from managers emphasizes taking ownership once changes are made, prompting the need for a risk assessment. The engineer faces a dilemma of either locking out the machine for a complete overhaul or addressing issues gradually while maintaining plausible deniability. Making alterations to an unsafe machine, especially in the program, increases liability in case of an accident. The recommended approach is to shut down the machine until all safety concerns are addressed. The debate arises regarding the responsibility of the last engineer to modify the machine and the ethics of leaving it operational. How should one respond to the employer in such a situation? Are there specific legal or regulatory guidelines to navigate this scenario effectively?

While I cannot provide specific legal advice, particularly in the United States, I can assure you of one thing: I value my peace of mind. I would steer clear of that situation as if it were radioactive.

The concept of "you touch it, you own it" appears to be a widely recognized principle. It is advisable not to touch anything until all safety concerns have been addressed and resolved, which may involve a financial cost. Personally, I would not even consider coming into contact with it unless it has been approved by safety protocols, possibly by experts like @ASF.

If someone ever tries to pressure me into engaging in unsafe practices, I would politely refuse. If the situation escalates or becomes threatening, I would request written documentation and promptly notify the appropriate safety regulatory agency (such as Worksafe) with this valuable evidence. It's crucial to address safety concerns in today's world, and there are hardly any justifications for compromising on safety standards for monetary reasons. "We will experience financial losses if this is not operational" should never be an acceptable excuse.

When it comes down to it, my approach is clear: if I'm ever in a situation where I'm being told or forced to work on a machine that I know is not safe, I will not hesitate to shut it down until every single safety concern is addressed. That's the path I would take. I would communicate to them that I will make the necessary changes, but it will take some time because the machine poses a serious risk to their staff. While I understand that regulations may differ in the US, in the UK there are protections in place to prevent employees from being fired for refusing to work in unsafe conditions. I stand firm in my belief that safety should always be the top priority.

I found myself in a dilemma when a manager insisted on replacing a faulty SSR without powering down the machine (rated at 480 volts). Despite my refusal, he approached another technician who also declined the risky task. In the end, the manager had no option but to follow safety protocols and shut down the machine. This incident prompted me to start exploring new job opportunities, leading me to eventually resign a few months later. The importance of workplace safety and adherence to protocol cannot be overstated.

In this situation, it's important to prioritize safety over expedience or productivity. The engineer should express their concerns to the employer about the apparent safety violations, stressing the potential for severe accidents or violations of OSHA standards, which could lead to legal issues. Instead of immediately acting on the employer's request, a thorough risk assessment, identifying and documenting all hazards, needs to be performed. Only once this has been completed and safety measures have been implemented, operations can be resumed. Consultation with a legal expert familiar with industrial safety law would also be beneficial to understand the full spectrum of liabilities involved. Remember, no job is worth risking lives over. Safety first!

This is indeed a tricky situation. In my view, it's important to refer back to the ethos of engineering which necessitates maintaining the highest regard for safety and the public welfare. Ignoring safety hazards for the sake of operational efficiency is not only unethical but could open you up to potential legal consequences. Addressing these safety issues responsibly is not just about avoiding personal liability, it's about valuing human life and ensuring a safe working environment. Direct the employer to the Occupational Safety and Health Administration (OSHA), as they often have guidelines and regulations for these scenarios. Inform them that modifications to a non-standard machine could increase liability for everyone involved, not just the last engineer to work on it. It might be advisable to shut down the machine for a complete overhaul or, if feasible, replace it with a device in compliance with safety regulations.

In such a scenario, it is crucial to prioritize safety over operational needs. This includes not only personnel safety, but also adherence to legal and regulatory guidelines which exists to prevent harmful incidents and protect corporate accountability. Any modifications made, however minor, may inadvertently introduce additional risks and increase liability. Therefore, making changes to an unsafe machine, without addressing underlying safety issues first, could be seen as a breach of professional duty and ethics. My recommendation would be to firmly yet diplomatically communicate to the employer the pressing nature of these safety issues and the legal implications involved. It may also be beneficial to consult a corporate lawyer or a professional familiar with industrial safety regulations to understand the potential liabilities and actions needed to address them properly. The laudable action in this case is to lockdown the machine until compliance to safety standards is ensured. Remember, it's always safety first.

In such a situation, clear communication with the employer is crucial. The engineer should outline the specific risks associated with operating the machine in its current state, the potential hazards involved if an accident occurs, and the potential liability. It might also be beneficial to cite specific regulatory guidelines or standards related to workplace safety, like those from OSHA. Moreover, the argument can be put forth that a complete machine overhaul, while possibly expensive and time-consuming in the short term, can lead to more efficient and safer operations and ultimately save the company from any accident-related costs and damage to its reputation. Remember, we all share responsibility for maintaining a safe workplace, and this situation should be treated as not just an individual’s but a collective ethical dilemma.

This is a tough situation, and I can definitely sympathize with the engineer's dilemma. The key here lies in prioritizing safety and ethics over short-term operational gains. I think the best course of action is to clearly communicate the risks associated with making any modifications to the machine without addressing its fundamental safety issues. Documenting everything and potentially escalating the concerns to higher management or even regulatory bodies is crucial, as it mitigates personal liability and reinforces the importance of compliance with safety standards. Ultimately, it's about protecting colleagues and ensuring a safe work environment—no modification is worth risking someone’s life. Do you think involving safety representatives or external auditors could strengthen the case for shutting down the machine for necessary upgrades?

It's a tough situation, but prioritizing safety must come first. I'd suggest having an open conversation with the employer, emphasizing that making modifications on a machine that doesn’t meet safety standards is not just ethically questionable, but could also lead to serious legal repercussions if an accident occurs. Documenting your concerns and referring to relevant safety regulations can help frame the discussion. It could be beneficial to advocate for a complete shutdown until all safety protocols are established—this not only protects workers but also shields the employer from liability in the long run. Remember, it's about creating a safe work environment first and foremost; the operational efficiency can always be rebuilt, but safety is non-negotiable.

This is definitely a tricky situation, but I think the priority should always be on safety first, no matter what pressures might come from management. It's vital to document everything and communicate clearly with the employer about the risks involved with making any modifications to an unsafe machine. If you express your concerns regarding potential liability and compliance with safety regulations, you might push for a complete overhaul rather than piecemeal fixes. There are legal guidelines that emphasize an engineer's duty to protect the health and safety of the public, so it could be worth citing those to make your case stronger. Ultimately, standing firm on safety standards not only protects you but also upholds the integrity of the workplace.
