The purpose of calibrating instruments is to ensure readings from an instrument are consistent with other measurements to determine the accuracy of the instrument reading and also to establish the reliability of the instrument i.e. that can be trusted and therefore all the instruments should be calibrated in order to ensure that all the readings and all the systems of the machines to be used allow faster processes and of course with lesser errors.

It is important to calibrate instruments prior to their use in order to measure accuracy and comparison of a measuring instrument that has a standard to determine the possible errors in a specific scale and also  reduces the risk of serious accidents, severe illnesses, poisonous gases, flammable gas explosions and even death since if the instruments are not well-calibrated before-head then there are risks that may include: divers face specific physical and health risks when scuba diving since there can be the loss of breathing gas supply due to faulty instruments.

Various hazards during calibration which include flammable materials, such as gases, mists, vapors or combustible dust which may lead to potentially explosive environments such as gas pipelines, rigs, and processing plants and oil refineries.
