Unsafe practices can easily creep into the workplace. Sometimes it’s due to worker inexperience. Other’s it may a result of time pressure to complete a job. Regardless of the cause, if you notice that safe working practices are being compromised you have the right to execute a stop work authority in order to sort the problem out.
Confer with your colleagues. Establish what the correct safety procedure is. And then, work together to reinstitute the proper procedure. Your stepping forward to take such a pro-active measure could prevent a disaster.
