Media Statement - Friday 7th May 2021

Massy Gas Products continues to service hospitals and health facilities

Massy Gas Products is the Premier Oxygen supplier to Trinidad and the Southern Caribbean through its partnerships with key oxygen generating facilities in the country and has significant capacity to meet unexpected demand. This includes a well devised infrastructural plan with the nation’s hospitals to meet current demands based on the bed spaces available.

As a result of the current state of affairs, Massy Gas Products has been proactively procuring equipment to increase its delivery capability to meet unanticipated demand.

In addition, with the increase of COVID-19 positive cases across Trinidad and Tobago, Massy Gas Products has been engaging with all of its stakeholders including the Ministry of Health and the Regional Health Authorities to ensure oxygen availability either through liquid oxygen and/or delivery of cylinders to hospitals and health facilities.

It has noted a significant increase in demand from private individuals who are seeking to purchase medical oxygen cylinders for personal use in the case of an emergency. At this time, the organisation says it is unable to meet those demands from private individuals, but it remains committed to certifying and filling cylinders that are privately owned. We wish to reiterate we will not be entertaining the purchase of medical oxygen cylinders for personal use, but only certifying and filling cylinders where applicable.

Massy Gas Products wishes to assure the public that there is no shortage in the availability and supply of medical oxygen to medical facilities. The company urges the population to continue adhering to the protocols set by the Ministry of Health and not from unverified sources.
