PELAMPUNG PENANDA PERMUKAAN (SMBS) DAN PELAMPUNG PENANDA PERMUKAAN TERTUNDA (DSMBS)<\/span><\/strong> adalah perangkat keselamatan yang umum dan penting. Tabung tiup berwarna cerah ini, kadang-kadang disebut sosis keselamatan, adalah peralatan penting yang harus dibawa oleh penyelam pada sebagian besar penyelaman. Penyelam paling sering menggunakannya sebagai alat pemberi isyarat untuk menandai lokasi mereka di bawah permukaan dan memperingatkan lalu lintas kapal. Penyelam teknis dapat menggunakan DSMB sebagai alat bantu untuk memenuhi kewajiban dekompresi. Tim penyelamat dapat menggunakannya jika ada penyelam yang mengalami kesulitan, seperti halnya penjaga pantai menggunakan tabung penyelamat di permukaan. Ada beberapa mitos dan kesalahpahaman tentang DSMB, dan banyak penyelam yang menggunakannya secara tidak tepat dan tidak efektif.<\/p>\n\n\n\n

\n

TERMINOLOGI<\/span><\/strong><\/p>\n\n\n\n

A DSMB is technically an SMB, but an SMB is not a DSMB. Divers can deploy a DSMB on the surface or from depth thanks to an over-pressurization valve (OPV). This valve allows air to escape and relieves the gas that expands, according to Boyle\u2019s Law. An SMB\u2019s design, which lacks an OPV, means it should be inflated only at the surface. If you deploy an SMB from depth, it will sustain physical damage from overexpansion as it ascends. This article will refer to DSMBs as their applications and features are more extensive than their SMB counterparts.<\/p>\n\n\n\n

SPESIFIKASI<\/span><\/strong><\/p>\n\n\n\n

DSMBs are available in various sizes, shapes, and colors \u2014 some are more practical than others. A 4-foot DSMB is sufficient for divers to learn the deployment techniques for training purposes. Outside of a training environment, divers should use at minimum a 6-foot DSMB, which provides better visibility to surface support and other boats, especially in unfavorable seas with large swells. It also offers sufficient lift to avoid being dragged underwater while the diver is ascending.<\/p>\n\n\n\n

Oranye dan kuning adalah warna yang paling umum dan menawarkan visibilitas terbaik, tetapi tidak ada warna standar industri. DSMB juga tersedia dalam warna merah muda, putih, hijau, dan bahkan hitam, tetapi beberapa warna tidak mudah terlihat di permukaan karena pantulan dan pembauran pada kondisi siang hari tertentu. Sebagian produsen menambahkan strip reflektif dan selongsong tipis yang bening di bagian atas untuk mengakomodasi strobo atau lampu kimia untuk digunakan dalam kondisi rendah cahaya.<\/p>\n\n\n\n

Beberapa penyelam menunjuk warna DSMB tertentu untuk mengomunikasikan pesan yang berbeda kepada personel pendukung di permukaan. Praktik ini paling umum dilakukan dalam penyelaman teknis. Misalnya, DSMB oranye dapat mengomunikasikan bahwa semua penyelam dalam keadaan selamat dan baik-baik saja, dan DSMB kuning dapat mengomunikasikan suatu keadaan darurat. Sebuah batu tulis atau halaman buku catatan bawah air yang dilampirkan pada DSMB kuning dapat menentukan masalah dan menjelaskan tindakan intervensi yang diperlukan dari dukungan permukaan. Tentu saja, sistem ini hanya berfungsi jika semua penyelam menyetujui satu rencana yang telah ditetapkan sebelumnya. Apa pun warnanya, semua penyelam harus mempertimbangkan untuk menulis nama mereka dalam huruf besar pada DSMB mereka sehingga bantuan permukaan dapat lebih mudah mengidentifikasi penyelam di bawah.<\/p>\n\n\n\n

TEKNIK<\/span><\/strong><\/p>\n\n\n\n

Some divers are adamant about using a reel instead of a spool or vice-versa. Divers should weigh the pros and cons of each and decide based on their personal diving needs. Each has its advantages \u2014 a reel is easier to deploy, but a spool is more difficult to jam.<\/p>\n\n\n\n

Para penyelam juga memperdebatkan apakah akan memasang secara permanen (pre-rig) spool atau reel ke DSMB untuk menyiapkannya agar dapat digunakan dengan cepat atau membiarkannya dipasang di bawah air. Haruskah penyelam menjepitkan DSMB langsung ke BCD mereka atau menyimpannya di saku atau kantong? Setiap penyelam harus mengevaluasi kebutuhan mereka dan memutuskan opsi mana yang paling praktis untuk semua pertimbangan ini.<\/p>\n\n\n\n

Ada banyak pendapat yang kuat mengenai mengembangnya DSMB. Haruskah Anda mengembang secara lisan? Bagaimana dengan menghembuskan napas dari tahap kedua atau membersihkan gurita ke bagian bawah yang terbuka? Bagaimana dengan memasang inflator bertekanan rendah dari baju kering atau BCD? Semua metode dapat dilakukan dengan pelatihan yang tepat dan latihan rutin.<\/p>\n\n\n\n

PERTIMBANGAN KEAMANAN<\/span><\/strong><\/p>\n\n\n\n

Ada beberapa masalah keselamatan universal yang harus diperhatikan setiap kali menggunakan DSMB. Penyelam tidak boleh menjepitkan reel atau spool pada diri mereka sendiri selama pemasangan karena jika macet, daya apung yang berlebihan dapat menyebabkan pendakian yang cepat. Jika Anda menjepitkan reel atau spool setelah DSMB sudah berada di permukaan, perahu yang lewat atau pejalan kaki yang ingin tahu dapat menarik tali, yang sekali lagi menyebabkan pendakian yang cepat.<\/p>\n\n\n\n

Selama menggunakan DSMB, ingatlah bahwa lambat itu halus, dan halus itu cepat. Penyelam harus menjaga agar semua tali tetap kencang dan sejauh mungkin dari tubuh mereka. Menjaga jarak ini akan mengurangi kemungkinan terjerat. Jika ada kelonggaran berlebih pada tali, luangkan waktu sejenak untuk mengatasinya. Masalah dapat bertambah dengan cepat, dan tali itu tidak kenal ampun jika seorang penyelam terjerat.<\/p>\n\n\n\n

Penyelam harus memiliki alat pemotong yang mudah diakses setiap kali mereka menggunakan DSMB. Jika memungkinkan, seorang rekan penyelam harus berada di dekatnya untuk mengintervensi jika terjadi kegagalan atau gangguan dalam pemasangan.<\/p>\n\n\n\n

Yang paling penting, penyelam harus berlatih. Menjadi mahir dalam menggunakan DSMB membutuhkan waktu. Pergilah ke kolam renang setempat atau lokasi perairan terbatas lainnya dengan teman Anda dan praktikkan setiap langkah proses, mengidentifikasi area yang kurang. Mintalah bantuan instruktur dan mentor. Jangan takut gagal, karena begitulah proses belajar dan memori otot terjadi. Di akhir setiap penyelaman, pertimbangkan untuk menggunakan DSMB. Pengulangan akan menciptakan kemahiran dan kenyamanan dengan keterampilan yang harus dimiliki setiap penyelam. AD<\/p>\n<\/div>\n\n\n\n

DSMB dengan panjang minimal 6 kaki akan membantu memastikan jarak pandang yang memadai<\/strong>.<\/span><\/p>\n<\/div>\n<\/div>\n\n\n\n
