On Site Mezuzah Checking In Factories And Plants Leave a comment Blog: Diary of a sofer: See the issues that Rabbi Michaels deals with on a daily basis. April 16, 2013 Checking mezuzos in factories and plants presents many special challenges. My specialized tool kits are the product of many years of experience in on site mezuzah checking. Bring the right tools to the job is the key to onsite mezuzah checking. Special sanitary jackets had to be worn on the floor of the factory. Care must be taken in factories to stay out of the way of the constant activity and yet still get to all the mezuzos. Melech Michaels at work checking the mezuzos in a small side room of the factory. A good numbering system must be used in order to keep track of the large amount of mezuzos. My son Zerach cutting through a corroded metal case. Sometimes this is the only way to get to the mezuza. Harsh factory conditions resulted in serious damage to some of the mezuzos. Care must be taken in a factory environment. You always have to pay attention. I’m not sure what Adina Sara Michaels was doing on a mezuzah house call at a factory!
