CP Gun operation manual
1. Overview
The CP Gun is designed for situations where a few contact CP readings are required. This diver-held
probe can be stored easily on a tool belt when not needed by the diver. The CP Gun outperforms all
other bathycorrometer-type devices on the market in accuracy and convenience. Longer battery life,
interchangeable freshwater / seawater electrodes and ultra-bright LED displays (for limited visibility situations) make the CP Gun the most user-friendly diver-held CP probe available. The dual electrodes and
readouts allow verication of the reference electrodes even as the diver works.
2. Scope
The purpose of this document is to instruct the user how to use and maintain the CP Gun, including:
taking potential readings and replacing the elements and batteries.
3. Health and safety
3.1 General
It is the intention of Deepwater Corrosion that all test and inspection procedures are to be carried
out in a safe manner in accordance with the Health and Safety at Work Act and any other relevant
legislation. If required by the client, Deepwater personnel will attend any site safety induction courses
before carrying out on-site work.
3.2 MSDS
Where applicable, substances hazardous to health shall be listed and itemized in the form of a register.
Health and safety data sheets for all hazardous substances shall be kept in a le for reference. Site
personnel shall be issued copies of health and safety data sheets relevant to their work activities.
4. Risk assessments
4.1 General hazards
4.1.1 Site safety - There are various risks associated with working on any site; Regulations re-
quired by the site owner/operator should be observed.
4.1.2 Personal Protective Equipment (PPE) - Eye protection and disposable rubber gloves
should be worn as a minimum of personal protective equipment when maintaining the CP Gun, in
addition to any other equipment required by the site operator or deemed necessary by the task.
4.2. Specic hazards
4.2.1 Measuring potentials - The contact tip of the probe is very sharp and can cause serious
damage to the user if not handled with care. It should NEVER be used to remove marine growth or
coatings.
4.2.2 Impressed Current Cathodic Protection (ICCP) is present- Transformers should be
turned off BEFORE any person enters the water in that area.
4.3 Environmental hazards
The copper (II) sulphate, deionized gel solution contained within the Cu / CuSO4 reference electrodes is potentially hazardous. Observe all federal, state and local regulations when disposing of this
substance. Please ensure that proper personal protective equipment (PPE) is worn during disposal.
For further information, please refer to the MSDS.
