発刊に寄せて

冷凍設備は、住宅やビルの空調用をはじめ、冷凍冷蔵倉庫、食品工場やレジャー施設など、私たちの生活に欠くことのできない様々な分野で利用されています。
これらの設備には冷媒ガスとして、ＣＦＣやＨＣＦＣが利用されてきました。これらのガスはオゾン層保護対策として生産消費が規制されていますが、温室効果も大きい物質であり、代替として主にＨＦＣ（代替フロン）への転換が進んできました。ＨＦＣはオゾン層を破壊しないものの、二酸化炭素の１００倍から１００００倍以上の大きな温室効果があると言われています。
平成２８年１０月には、ＨＦＣを新たにモントリオール議定書の規制対象とする改正提案が採択されました。
（キガリ改正）また、ＨＣＦＣであるフルオロカーボン２２は、成層圏のオゾン層破壊防止や地球温暖化防止など地球環境保全の観点から、２０２０年以降製造や輸入ができなくなりました。
現在は、二酸化炭素とアンモニアを冷媒とする設備や、これまで微燃性ガスとされていた
R32、HFO1234yf、HFO1234ze などの新冷媒を使用した設備が利用され始めています。
これらの冷媒ガスについては、高い圧力、毒性、可燃性などの危険性から、高圧ガス保安法により冷凍設備の設置や変更に際しては許可が必要であるなど様々な規制がかけられていまし
たが、平成２８年１１月と平成２９年７月の法改正により大きく規制緩和されました。これにより、届出（５０トン未満）範囲も広がり大きく緩和されました。
本マニュアルは、高圧ガス保安法に基づく第二種製造者が自らに課せられた法的責務を履行し、社会的要請に応えるため、（一社）神奈川県高圧ガス保安協会が作成したものです。
今回の改訂では、平成２８年１０月２８日付け及び平成２９年７月１０日付けの高圧ガス保安法施行令の改正、平成３０年４月１日付け制定の神奈川県高圧ガス保安法行政指導指針、令和２年１２月２８日付けの押印を求めている手続等に関して押印を不要とする一部改正、令和３年１０月２７日付けの冷凍設備内で使用されるヘリウム等の規制緩和の改正等が盛り込まれています。
冷凍施設設置時の手続きにとどまらず日常的な保安管理にも役立つように作成されていますので、事業者の皆様には積極的にご活用いただき、自主保安の推進に努めていただきたいと思います。

届出書類様式一覧

当協会は、昭和６０年に高圧ガス取締法による「第二種製造者用 冷凍関係マニュアル」を作成し、平成１７年に内容を全面的に改定し、事業者の皆様方には冷凍設備の保安確保に広く活用をいただいてきたところであります。
今回の改訂は前回発刊以降の法規制事項の追補の他、高圧ガス関係の許認可業務の一部の指定都市への権限移譲及び権限移譲に伴う神奈川県高圧ガス保安法指導指針の制定等に伴い、各項目を見直し修正を加えるとともに、定期自主検査、日常点検の項目を具体的に示し、点検の内容を明確にしました。事業者の方々には自主保安による保安管理が強く望まれる中、本マニュアルを有効に活用し適切な管理と保安の確保に資すれば幸いです。
終りに本書は神奈川県くらし安全防災局防災部消防保安課及び政令指定都市消防局のご協力により作成されたものであり、ここに関係された方々のご努力に心から感謝申し上げます。
