Contract wording to Hold you harmless and avoidance of holding other parties harmless. Contracts should be very specific to services provided and should include payment terms and conditions. Documented written practices and procedures. Reports that define limitations and do not provide warranties or guarantees. Review of any bids that require insurance certificates or extended tail coverage to ensure that your policy will apply as required by the contract.
Professional ethics are a key component when liability arises.
Guidance on professional conduct can be found in the American Industrial Hygiene code of ethics. Education, certifications, licenses and professional development all play key roles in ascertaining your knowledge and integrity. While every liability claim is unique, claims against professionals are emotionally charged, as inevitably they are when claimants attack one's professional competence. Thus, the handling of professional liability claims must be undertaken with extreme sensitivity. It is critical that professionals promptly report both claims and potential claims to the insurer.
