Companies may substitute registrants without prior notice or penalty. Full refund available for cancellations up to three (3) weeks prior to workshop date. 50% refund up to one (1) week prior to workshop. Cancellations made less than seven (7) days prior to workshop start date will be charged, but an 80% credit may be applied toward a future program. No-shows receive no credit and will be billed. In the event that the Division of Chemical Health and Safety is forced to cancel a workshop due to lack of registration or other causes, CHAS will notify participants at least ten (10) days in advance by email. We will notify you by email as soon as we know that the workshops will be held, i.e. we have sufficient registrants to present the workshop. CHAS suggests fully refundable air fares be used due to the potential of workshop cancellation. CHAS will not be responsible for penalties caused by these types of fares in the event of workshop cancellation.
