The Health Information and Quality Authority (HIQA) has published 48 inspection reports on residential centres for older people.
Of the 48 reports, inspectors found evidence of good practice and compliance with regulations and standards in 39 centres.
In general, these centres were found to be meeting residents' needs and delivering care in line with the national standards and regulations.
But the report found St Eithne's Rest Care Centre in Roscommon had a lack of staff - leaving residents unsupervised, and significant fire safety issues.
At St Eithne's, HIQA inspectors found that adequate precautions had not been taken to ensure that residents were protected from the risk of fire.
They said adequate arrangements had not been made for maintaining all means of escape, building fabric and building services.
A designated escape route was impeded by office furniture, inspection certificates were not available for the electrical installation and there were no records in the fire and safety register regarding the maintenance or inspection of fire doors.
They also observed that closers had been removed from some doors that were intended to be fire doors.
It also found that staff were not Garda vetted in HSE centres Ballinasloe and Skibbereen.
While HIQA found Corrandulla Nursing Home in Galway was 'unclean' and residents were not supervised.
And at Mount Carmel Community Hospital in Dublin there were 'significant' fire safety risks.
The HIQA inspector was "not assured" that the bedroom doors in the 'Maple' section of the centre would achieve their required fire performance.
"Most bedroom doors in this part of the centre were not fitted with closers, intumescent strips, smoke seals, appropriate ironmongery or manufacturer tags to confirm their likely fire performance," HIQA said.
"In various parts of the centre the compartment doors were fitted with a manufacturer applied tag indicating their fire rating.
"In some cases the indicated fire rating was lower than would be required by their purpose and location."
Inspectors found evidence of non-compliance in nine centres overall.
In these centres, the provider failed to ensure that the service delivered to residents was "effectively monitored", in line with the regulations and standards.
Inspectors identified non-compliances in areas including governance and management, residents' rights, staffing, training and staff development.
Lapses were also seen in premises, risk management, infection control and medicines and pharmaceutical services.
