Yes, it is safe. T-shirt printing machines are designed with technology and materials that allow them to perform their duties while keeping the user safe. For models that require assembly such as the VIVOHOME 8 in 1 Heat Press, ensure that you adhere to the instructions availed in the manufacturer’s manual to prevent the occurrence of an accident within your home. For those that have already been assembled, make sure that the power supply is constant and robust and that the work environment is free of any substances that could cause harm to you or your property.
