For the general public one of the more visible manifestations of Civil Defence is the first aid and ambulance cover provided at large events such as concerts, equestrian competitions. This however is only a part of the casualty service of the Civil Defence. All members are trained in first aid which is an essential component of rescues, searches, stewarding, firefighting and other duties. Others train more extensively in areas such as basic life support and ambulance procedures. First aid training is also provided to the wider community by Civil Defence. In a major emergency Civil Defence personnel and equipment would assist Health Board ambulance services in the initial treatment and transport to hospital of the injured.

Laois Civil Defence currently has 1 Nurse, 1EMT, 2 Trainee Nurses, 1 Advanced First Aider, 1 EMFR (Emergency Medical First Responder) and numerous First Aiders. No. 3 Base in Durrow is currently running a First Aid Course to ensure all members are at least to this level. Members are also preparing to take Advanced First Aid exams in the near future.

Laois Civil Defence operates a 1995 Volkswagen LT31 Wilker ambulance.
The ambulance is where possible stocked to HSE (Health Service Executive) Ambulance Service standards. It has recently gotten a face lift with the addition of modern markings. (See Pic). The ambulance is backed up by four-wheel drive vehicles which carry equipment and personnel in off-road or mountainous conditions.
