Task: Adding Perone to R-10
Workplace area: Co Blend Background: On May 28, 2013 a hazard assessment for Proper Protection Equipment (PPE) was performed to specify the required PPE for employees in the Co-Blend operation involved in manually adding Perone to the R-10 Tank. The Co-Blend Area process consists of both automated and manual activities. Small quantities of raw materials (such as hydrogen peroxide and parabens) are added manually, while the addition of larger quantities is automated. Hydrogen Peroxide is often added to the R-10 Tank (via PR-1) tank in order to neutralize chlorine and provide anti-microbial protection. The use of Perone, common name Hydrogen Peroxide, is a corrosive substance that poses risk to the employees. Based on chemical splashing concerns, the hazard assessment was conducted to identify the need for an additional Safety Shower and Eye Wash station to be installed in close proximity of the procedure. A walk through survey identified the activities that may create hazards to the employees. The activities were grouped according to what part of the body might need PPE. The enclosed worksheet (see Page 4) is provided to aid in the hazard assessment. Description of Procedure:
The description of the procedure is as follows:
The employee begins with the of use an HMI Screen to allow the employee to interface with the control system, manually manipulate system components, and set pre-determined weights for raw materials. The employee will then obtain the labeled Perone bucket from its designated location. The bucket and the lid are pre-rinsed before use. The amount of Perone varies depending on the mixture involved that day. Thus before pumping the Perone into the bucket, the employee must a tare weighing station with bucket on top, in order to determine the net weight of Perone needed. The employee then pumps the designated amount of Perone into the bucket. Upon pumping
