What reasoning is provided against switching to "on call" service?

The reasoning against switching to "on call" service primarily hinges on the concern that it may be too late after an emergency has occurred. This highlights the critical nature of prompt responses in emergency situations. When first aid and safety services are only provided on an on-call basis, there is a risk that immediate assistance may not be available during urgent times, thereby compromising the safety and well-being of individuals in need.

The effectiveness of safety and first aid services relies heavily on their availability when required. If services are not proactively managed and readily accessible, the delay in response during emergencies can lead to severe consequences, including worsening health outcomes, increased risk of injury, or loss of life. This perspective emphasizes the importance of consistent and reliable service deployments over reactive measures that may not address immediate safety needs.
